Subject: [Bug libffi/97166] New: libffi build issue when compiling with -mcpu=power10
Date: Tue, 22 Sep 2020 17:53:09 +0000 [thread overview]
Message-ID: <bug-97166-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97166
Bug ID: 97166
Summary: libffi build issue when compiling with -mcpu=power10
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libffi
Assignee: unassigned at gcc dot gnu.org
Reporter: bergner at gcc dot gnu.org
Target Milestone: ---
When building libffi with -mcpu=power10, we're seeing the following linker
error.
libtool: link: gcc -shared -fPIC -DPIC src/.libs/prep_cif.o src/.libs/types.o
src/.libs/raw_api.o src/.libs/java_raw_api.o src/.libs/closures.o

src/powerpc/.libs/linux64.o: in function `ffi_call_LINUX64':
(.text+0x40): call to `ffi_prep_args64' lacks nop, can't restore toc; (toc
save/adjust stub)
/home/bergner/gcc/install/gcc-fsf-mainline-power10/bin/ld: final link failed:
bad value

Makefile:1028: recipe for target 'libffi.la' failed
This ends up being a bug in some POWER specific libffi asm code that doesn't
know about our new to POWER10 PCREL support. This bugzilla is to track syncing
the fix to libffi into GCC version of libffi, which is being tracked upstream
