arch/arm64/kernel/vdso/gettimeofday.S in stable/linux-4.19.y failed to build with LLVM_IAS=1 #1349
Comments
It seems like IAS cannot parse the comma between macro name and arguments. The following diff fixed the problem. ---

This is "fixed" by the rewrite of the vDSO into C: https://git.kernel.org/linus/28b1a824a4f44da46983cd2c3249f910bd4b797b That diff seems fine to carry downstream if you do not want to do something similar to Android (which was a pretty massive backport series): https://android-review.googlesource.com/c/kernel/common/+/1294668 |
Ah I see! Thanks for the link. The backports do look massive. Edited: I sent a patch for stable 4.19 branch: https://lore.kernel.org/stable/CA+SOCLL28Hej9zMmKJpU5vffVGviDo59uG=kWm0zPtCyZodR5g@mail.gmail.com/T/#t |
I provided some feedback to try and move this along upstream: https://lore.kernel.org/r/YJMJAiwMPqlWmr8Y@archlinux-ax161/ |
Thanks for the feedback! Will update the patch. |
Patch is accepted and queued for the next 4.19 release in a couple of days: https://lore.kernel.org/r/16206352882063@kroah.com/ |
LLVM's integrated assembler appears to assume an argument with default value is passed whenever it sees a comma right after the macro name. It will be fine if the number of following arguments is one less than the number of parameters specified in the macro definition. Otherwise, it fails. For example, the following code works: $ cat foo.s .macro foo arg1=2, arg2=4 ldr r0, [r1, #\arg1] ldr r0, [r1, #\arg2] .endm foo, arg2=8 $ llvm-mc -triple=armv7a -filetype=obj foo.s -o ias.o arm-linux-gnueabihf-objdump -dr ias.o ias.o: file format elf32-littlearm Disassembly of section .text: 00000000 <.text>: 0: e5910001 ldr r0, [r1, #2] 4: e5910003 ldr r0, [r1, torvalds#8] While the the following code would fail: $ cat foo.s .macro foo arg1=2, arg2=4 ldr r0, [r1, #\arg1] ldr r0, [r1, #\arg2] .endm foo, arg1=2, arg2=8 $ llvm-mc -triple=armv7a -filetype=obj foo.s -o ias.o foo.s:6:14: error: too many positional arguments foo, arg1=2, arg2=8 This causes build failures as follows: arch/arm64/kernel/vdso/gettimeofday.S:230:24: error: too many positional arguments clock_gettime_return, shift=1 ^ arch/arm64/kernel/vdso/gettimeofday.S:253:24: error: too many positional arguments clock_gettime_return, shift=1 ^ arch/arm64/kernel/vdso/gettimeofday.S:274:24: error: too many positional arguments clock_gettime_return, shift=1 This error is not in mainline because commit 28b1a82 ("arm64: vdso: Substitute gettimeofday() with C implementation") rewrote this assembler file in C as part of a 25 patch series that is unsuitable for stable.
