Subject: LLVM/clang ias build fails with unsupported arguments '-mpower4' and '-many' to option 'Wa,'
Date: Mon, 13 Sep 2021 11:48:21 +0200 [thread overview]
Message-ID: <62cc7e62-d072-7b16-8b6c-006f067b1ed7@molgen.mpg.de> (raw)
Dear Linux folks,
Building Linux with LLVM’s integrated assembler fails with the error
below [1].
```
$ ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- make LLVM=1
LLVM_IAS=1 -j72 pseries_defconfig arch/powerpc/kernel/vdso32/gettimeofday.o
...
arch/powerpc/kernel/vdso32/gettimeofday.S:72:8: error: unsupported
directive '.stabs'
.stabs "_restgpr_31_x:F-1",36,0,0,_restgpr_31_x; .globl _restgpr_31_x;
_restgpr_31_x:
^
arch/powerpc/kernel/vdso32/gettimeofday.S:73:8: error: unsupported
directive '.stabs'
.stabs "_rest32gpr_31_x:F-1",36,0,0,_rest32gpr_31_x; .globl
_rest32gpr_31_x; _rest32gpr_31_x:
^
```
The LLVM developers are not planning on implementing this, as Stab has
been succeeded by DWARF [2].
Kind regards,
Paul
