I am very excited about the binary release of gcc-toolchain, but I run into problems trying to compile something as simple as: int main() { return 0; } $ ~/morello-gnu/bin/aarch64-none-elf-gcc -march=morello -O0 -nostdlib hello.c /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/bin/ld: warning: cannot find entry symbol _start; defaulting to 0000000000400000 $ ~/morello-gnu/bin/aarch64-none-elf-gcc -march=morello -O0 hello.c /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/bin/ld: /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/lib/hybridcap/libc.a(lib_a-exit.o): in function `exit': /data/jenkins/workspace/GNU-toolchain/morello-trunk/src/newlib-cygwin/newlib/libc/stdlib/exit.c:70: undefined reference to `_exit' /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/bin/ld: /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/lib/hybridcap/crt0.o: in function `_start': /data/jenkins/workspace/GNU-toolchain/morello-trunk/src/newlib-cygwin/libgloss/aarch64/crt0.S:360: undefined reference to `__init_global_caps' /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/bin/ld: /data/jenkins/workspace/GNU-toolchain/morello-trunk/src/newlib-cygwin/libgloss/aarch64/crt0.S:361: undefined reference to `__processRelocs' /home/lord/morello-gnu/bin/../lib/gcc/aarch64-none-elf/10.1.0/../../../../aarch64-none-elf/bin/ld: /data/jenkins/workspace/GNU-toolchain/morello-trunk/src/newlib-cygwin/libgloss/aarch64/crt0.S:365: undefined reference to `initialise_monitor_handles' collect2: error: ld returned 1 exit status Any suggestions on what I am doing wrong?

[To be committed] Testsuite fixup for linux build

[To be committed] Avoid adjusting an eh_frame symbol into a section symbol plus offset

by Matthew Malcomson

GNU bfd linker removes duplicate CIE and FDE entries in the exception handling information. When it does this entries in the .eh_frame section end up in different positions to where they were originally. In order to account for that, when the linker removes an FDE/CIE entry from one object's .eh_frame section in order to prefer an equivalent entry in another object's .eh_frame section, the linker adjusts symbols which were pointing to the first entry to point to the second. If the assembler has changed symbols pointing into the .eh_frame section such that they are now described by a section symbol plus offset, the linker can not perform this transformation. This means that symbols can end up pointing at different information than they originally pointed at. NOTE1: This changes the behaviour of this on *all* targets. As it stands that seems like the correct approach since the linker behaviour that we are accounting for is a general behaviour. On top of that, this translation should not make a change in functionality if the linker behaviour were not enabled for some target (since without the linker behaviour this transformation should not affect anything -- which is why it's believed to be safe in the first place). However it is still important to note that we have not actually tested these changes on other architectures. NOTE2: Since the GNU linker makes its decision to look for items to merge or not based on the *output* section name, there is a mapping between output sections and input sections that can be modified by the user, and we may not even be using the GNU linker in the first place, our patch can not be 100% accurate and robust when choosing which sections to avoid this adjustment. It is still desirable to avoid problematic adjustment in the common case of using the GNU linker with the default mapping between input sections and output sections. Though it may not be desirable to hard-code a feature of the default linker script at the time of writing this patch into GAS. Here we use the same check that the assembler uses in gas/dw2gencfi.c to identify a .eh_frame section. This has the benefits of being a check the assembler is using already (so the assembler is internally consistent) and matching the split that the default bfd linker scripts make between all input sections that said scripts name. E.g. the default linker script for aarch64-none-elf matches the following patterns for an output section named .eh_frame_hdr { *(.eh_frame_hdr) *(.eh_frame_entry .eh_frame_entry.*) } and matches the below for an output section named .eh_frame { KEEP (*(.eh_frame)) *(.eh_frame.*) }. The linker then applies the problematic transformation to the .eh_frame output section and not to the .eh_frame_hdr section. The check we use here makes a corresponding decision to all sections which would be caught by the above patterns. I.e. it avoids adjusting symbols in sections which would end up in the .eh_frame output section and does not avoid adjusting symbols in sections which would end up in the .eh_frame_hdr output section. NOTE3: This behaviour by itself is not causing any problems for us. The trigger for making this change (especially in morello binutils) is that when crtbeginT.o "registers" an object's exception handling information with a static glibc, it uses `adrp` and `add` to access the __EH_FRAME_BEGIN__ symbol. Currently the relocation on `adrp` is adjusted into a "section symbol plus offset" transformation (which ends up as exactly the start of the section symbol in the crtbeginT.o object), but the `add` instruction is not adjusted in this way. It is this *difference* that is problematic. It means that we can end up with a broken pointer using the .eh_frame page and the __EH_FRAME_BEGIN__ offset into a page. With base AArch64, both these instructions would be adjusted to point to the .eh_frame section of crtbeginT.o. This is still a buggy behaviour in the assembler due to the reasons given above, but it at least meant that the static glibc got a sensible pointer (though one starting after any exception frame information on the crti.o and crt1.o object files). With this change, both instructions stay pointing at __EH_FRAME_BEGIN__ in the object file. That means that the linker will leave both instructions pointing at the same place after de-duplication of exception information. That place is not guaranteed to be the start of the total exception frame information, but in practice it is always closer to the start of the debug frame than without having made this patch. We could have stopped static glibc from crashing by making sure that we accessed the .eh_frame section symbol for both instructions rather than using __EH_FRAME_BEGIN__ for both. This would behave in the same way as stock AArch64. This would mean that static glibc would not be affected by the particulars of how the GNU bfd linker merges CIE and FDE entries together. On the other hand it would mean that static glibc would never have the ability to unwind through start code in crt1.o and crti.o. I don't have a particularly strong opinion on which of these is the best approach, I chose this one since it gives the static glibc access to the full debug information for the moment. ############### Attachment also inlined for ease of reply ############### diff --git a/gas/testsuite/gas/aarch64/eh-frame-symbols.d b/gas/testsuite/gas/aarch64/eh-frame-symbols.d new file mode 100644 index 0000000000000000000000000000000000000000..8276648ea1c5ea1ce7cd945ecfdf952cd71a0911 --- /dev/null +++ b/gas/testsuite/gas/aarch64/eh-frame-symbols.d @@ -0,0 +1,24 @@ +# Checking that our relocations against the symbol __EH_FRAME_BEGIN__ are not +# transformed into relocations against the section symbol .eh_frame. +#as: -march=morello+c64 +#objdump: -dr + +.*: file format .* + + +Disassembly of section \.text: + +.* <get_eh_frame_begin>: + *[0-9a-f]+: ........ stp c29, c30, \[csp, #-64\]! + *[0-9a-f]+: ........ adrp c0, 0 <get_eh_frame_begin> + 4: R_MORELLO_ADR_PREL_PG_HI20 __EH_FRAME_BEGIN__ + *[0-9a-f]+: ........ adrp c0, 0 <get_eh_frame_begin> + 8: R_MORELLO_ADR_PREL_PG_HI20 \.eh_frame + *[0-9a-f]+: ........ add c0, c0, #0x0 + c: R_AARCH64_ADD_ABS_LO12_NC __EH_FRAME_BEGIN__ + *[0-9a-f]+: ........ add c0, c0, #0x0 + 10: R_AARCH64_ADD_ABS_LO12_NC \.eh_frame + *[0-9a-f]+: ........ ldp c29, c30, \[csp\], #64 + *[0-9a-f]+: ........ ret c30 + +#... diff --git a/gas/testsuite/gas/aarch64/eh-frame-symbols.s b/gas/testsuite/gas/aarch64/eh-frame-symbols.s new file mode 100644 index 0000000000000000000000000000000000000000..a10b59e034e15d048c5aef4ee1a82da9acd9e69e --- /dev/null +++ b/gas/testsuite/gas/aarch64/eh-frame-symbols.s @@ -0,0 +1,31 @@ +.section .eh_frame,"a" +.type __EH_FRAME_BEGIN__, %object +__EH_FRAME_BEGIN__: + +.text +.type get_eh_frame_begin, %function +get_eh_frame_begin: + .cfi_startproc purecap + stp c29, c30, [csp, -64]! + .cfi_def_cfa_offset 64 + .cfi_offset 227, -64 + .cfi_offset 228, -48 + adrp c0, __EH_FRAME_BEGIN__ + adrp c0, .eh_frame + add c0, c0, :lo12:__EH_FRAME_BEGIN__ + add c0, c0, :lo12:.eh_frame + ldp c29, c30, [csp], 64 + .cfi_restore 228 + .cfi_restore 227 + .cfi_def_cfa_offset 0 + ret + .cfi_endproc + +.global _start +.type _start, %function +_start: + mov x0, #0 + ret + +# .zero 0xff0 - 0x38 - 0x78 +.zero 0xff0 - 0x38 diff --git a/gas/write.c b/gas/write.c index 054f27987d51f1732afdc81bbc9e19a95160c53f..5301bbd465048208c51f9b12fb6479c765c9a5f4 100644 --- a/gas/write.c +++ b/gas/write.c @@ -878,6 +878,28 @@ adjust_reloc_syms (bfd *abfd ATTRIBUTE_UNUSED, continue; } + /* Avoid adjusting a relocation against a symbol pointing into a + ".eh_frame" section in an ELF binary.

[To be committed] Disable some symbol -> section_symbol + offset translations

by Matthew Malcomson

We're disabling transformations of relocations against symbols like this in the assembler when the relocation is against something in the GOT and when the relocation is against something which generates a capability. For entries in the GOT we disable this transformation since the GNU bfd linker relies on indexing into its internal representation of the GOT using symbols and does not distiinguish between entries using the same symbol but different offsets. Hence transforming multiple symbols into the same section symbol with different offsets would mean that at least one will get an incorrect value. Relocations which require the static linker to emit dynamic relocations in order to generate capabilities (CAPINIT and capability relocations into the GOT) require symbol information so that the dynamic linker can put correct permissions and bounds on those relocations. NOTE: We get to use an existing testcase for this change, but it showed up something strange about objdump. One `adrp` instruction has changed in the output so that it shows as pointing to a different location. This happens to be an `objdump` quirk. Objdump looks at the relocation associated with an address and attempts to include that relocation when determining what address to print out. This mechanism has two problems, one is that objdump does not account for the offset in that relocation (only the symbol). Another is that on an object file (i.e. not a final executable) the virtual memory address of all sections is zero. These combined mean that the vma is miscalculated, and the translation from vma to symbol is not injective. In other words: the extra change in morello-ldst-reloc.d on top of switching the relocation symbols is in order to account for an objdump bug and not a problem with this gas change. ############### Attachment also inlined for ease of reply ############### diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index a1bd6e1a769d968ed0bdb2b3dca7bc87732cc498..c8373b311dd14f3c53ce4099ab1ffee28d360e8a 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -9382,13 +9382,37 @@ check_mapping_symbols (bfd * abfd ATTRIBUTE_UNUSED, asection * sec, bfd_boolean aarch64_fix_adjustable (struct fix *fixP) { - /* We need size information of the target symbols to initialise - capabilities. */ - if (fixP->fx_r_type == BFD_RELOC_MORELLO_CAPINIT) - return FALSE; - switch (fixP->fx_r_type) { + /* The AArch64 GNU bfd linker can not handle 'symbol + offset' entries in the + GOT (it internally uses a symbol to reference a GOT slot).

[PATCH] libiberty: Account for CHERI alignment requirement in objalloc

by Alex Coplan

Hi, The calculation of OBJALLOC_ALIGN in include/objalloc.h ensures that allocations are sufficiently aligned for doubles, but on CHERI architectures it is possible that void * has a greater alignment requirement than double. Instead of deriving the alignment requirement from double alone, this patch uses a union to compute the maximum alignment between double and void *. This fixes alignment faults seen when compiling the binutils for pure-capability Morello. With this patch applied, the majority of binutils tests pass when the binutils themselves are compiled for purecap. This patch is a backport of commit a8af417a8a1559a3ebceb0c761cf26ebce5eab7f, initially upstreamed to Morello GCC. OK for morello branch? Thanks, Alex

[To be committed] Fix tests after rebase of 36b6002396d onto 8504495ada4

by Matthew Malcomson

When we started to account for function stubs when determining our PCC bounds and section bounds we stopped including padding to make PCC bounds precise in the highest section that should be included in the PCC range. Instead we put such padding *after* that section. Our patch handling IFUNC's was written in parallel, and its testcases were using the previous setup (where PCC padding was included in the last section). Hence when calculating a fragment that we should see in our testcase we took the highest address in the last RELRO section. After the application of both patches that approach no longer works. With the new mechanism for padding there is no longer in general a guarantee that any value in the section table could correspond to the PCC bounds (since the alignment of the first writeable section could be high enough such that the PCC bounds are somewhere between the end of the last RELRO section and the start of the first WRITE section). However for all these testcases the start of the first WRITE section seems good enough to not be flaky. ############### Attachment also inlined for ease of reply ############### diff --git a/ld/testsuite/ld-aarch64/morello-ifunc-a.d b/ld/testsuite/ld-aarch64/morello-ifunc-a.d index f36b0945cb554a841fa16dd58f96d7bec7da29ee..a9c3b65073dbd6dcd2c2af60e1bfca43957febb4 100644 --- a/ld/testsuite/ld-aarch64/morello-ifunc-a.d +++ b/ld/testsuite/ld-aarch64/morello-ifunc-a.d @@ -14,10 +14,11 @@ Idx Name Size VMA LMA File off Algn #record: PCC_START 0 \.[^ ]* +[0-9a-f]* ([0-9a-f]+) .* CONTENTS, ALLOC, LOAD, READONLY, DATA -#record: PCC_LAST_SIZE PCC_LAST_START #... - *[0-9]+ \.got\.plt *([0-9a-f]+) ([0-9a-f]+) .* + *[0-9]+ \.got\.plt *[0-9a-f]+ [0-9a-f]+ .* CONTENTS, ALLOC, LOAD, DATA +#record: PCC_END + *[0-9]+ \.[^ ]* +[0-9a-f]* ([0-9a-f]+) .* #...
