Bug ID: 26513
Summary: 629310abec8811510177101f3c7992dfd4be24dd breaks
assembling PowerPC Linux kernels
Product: binutils
Version: 2.36 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: natechancellor at gmail dot com
Target Milestone: ---
When building the Linux kernel for some PowerPC targets with LLVM + gas (since
LLVM's integrated assembler is not quite on par with some assembly used in the
Linux kernel) after 629310abec8811510177101f3c7992dfd4be24dd, the following
error occurs:
$ make -skj"$(nproc)" ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu- LLVM=1
O=out/ppc64 distclean pseries_defconfig arch/powerpc/kernel/entry_64.o
...
arch/powerpc/kernel/entry_64.S: Assembler messages:
arch/powerpc/kernel/entry_64.S:541: Error: junk at
end of line: `0b01010'
