Bug ID: 57265
Summary: Bootstrap failure on sparc-sun-solaris2.10 in
libquadmath
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: ahaas at airmail dot net
My builds have failed since April 15 when building 'libquadmath' after
completing the stage2/stage3 comparison. My last successful build was on April
14. The error below is taken from the 'config.log' file in the
'sparc-sun-solaris2.10/sparcv9/libquadmath' directory:
{ ... snip ... }
configure:3386: checking whether the C compiler works
configure:3395: ./a.out
ld.so.1: a.out: fatal: /export/home/arth/src/gcc-0512/./gcc/libgcc_s.so.1:

A bit of git bisecting leads to this change:

Use -z ignore instead of --as-needed on Solaris
* configure.ac (gcc_cv_ld_as_needed): Set
gcc_cv_ld_as_needed_option, gcc_cv_no_as_needed_option.
Use -z ignore, -z record on *-*-solaris2*.
(HAVE_LD_AS_NEEDED): Update comment.
(LD_AS_NEEDED_OPTION, LD_NO_AS_NEEDED_OPTION): Define.
* configure: Regenerate.
* config.in: Regenerate.
* gcc.c (init_gcc_specs) [USE_LD_AS_NEEDED]: Use
LD_AS_NEEDED_OPTION, LD_NO_AS_NEEDED_OPTION.
* config/sol2.h [HAVE_LD_AS_NEEDED] (USE_LD_AS_NEEDED): Define.
* doc/tm.texi.in (USE_LD_AS_NEEDED): Allow for --as-needed
equivalents. Fix markup.
* doc/tm.texi: Regenerate.

I'm able go get a successful build with the previous revision 197963, which is
'98c0d6572c62b325c1e8635df3d6b22003b83619' in my git checkout. In this
revision, the config.log contents from 'sparc-sun-solaris2.10/sparcv9' show
this test succeeding:
configure:3386: checking whether the C compiler works
configure:3395: ./a.out
configure:3399: $? = 0
configure:3414: result: yes
Thanks.
