Bug #: 50513
Summary: cross configurations fail to build
ipa-inline-analysis.o with -Werror
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: build
Severity: major
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: amylaar@gcc.gnu.org
Blocks: 44756
Host: x86_64-unknown-linux-gnu
Target: any cross
183 of 198 configurations in contrib/config-list.mk fail to build build with
this error:
../../../gcc/gcc/ipa-inline-analysis.c: In function ‘predicate_probability’:
../../../gcc/gcc/ipa-inline-analysis.c:485:8: error: comparison between signed
and unsigned integer expressions [-Werror=sign-compare]
../../../gcc/gcc/ipa-inline-analysis.c: In function ‘remap_edge_change_prob’:
../../../gcc/gcc/ipa-inline-analysis.c:2356:5: error: comparison between signed
and unsigned integer expressions [-Werror=sign-compare]
cc1: all warnings being treated as errors
(the other configurations fail for other reasons)
I have used a native compiler previously bootstrapped from the same sources.
I see that for the boostrap, ipa-inline-analysis.o was built once with
the bootstrap compiler, and twice with the previous stage g++. For the
cross-compilation, on the other hand, gcc is used (even though g++ is
also available), with the additional options:
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wc++-compat

Native builds of current trunk (mine is gcc-4.7-20110924 == r179148) also fail
in the same way, when configured with --disable-build-poststage1-with-cxx. The
reason is that PR50012 (a C++ FE diagnostics bug) causes some warnings in new
code to go undetected, until someone does a build in proper C mode.
Anyway, for this PR the fix should be:

Probably fixed by Richard Sandiford in r179268.
