Subject: [PATCH 0/6] Fix support for biarch compilers and cross cflags
Date: Tue, 21 Jun 2022 09:51:41 +0200 [thread overview]
Message-ID: <20220621075147.36297-1-pbonzini@redhat.com> (raw)
This series fixes two bugs with configure's cross compilation detection:
- first, --cross-cflags is not obeyed by pc-bios/ compilation
- second, on a ppc64le machine, the host compiler can be used for ppc64
tests/tcg; however, this is not being done because $cpu does not
match the target. Likewise, on an x86_64 machine the host compiler
can be used to build both i386 tests/tcg and pc-bios/optionrom, but
the special casing done by the configure script only covers the latter.
The two are related because, if only the first was fixed, pc-bios/optionrom
would use either the i386 or the x86_64 cflags depending on which cross
compiler was found. So patches 2-4 tackle not just the cross CFLAGS
problem with pc-bios, but also the biarch compiler problem with i386
and ppc. Patch 5 then covers the other biarch compilers.
The other two patches are just cleanups.
Supersedes: <20220607094031.1227714-1-pbonzini@redhat.com>
Paolo Bonzini (6):
pc-bios/optionrom: use -m16 unconditionally
configure, pc-bios/optionrom: pass cross CFLAGS correctly
configure, pc-bios/s390-ccw: pass cross CFLAGS correctly
configure, pc-bios/vof: pass cross CFLAGS correctly
configure: allow more host/target combos to use the host compiler
configure: write EXTRA_CFLAGS for all sub-Makefiles
