libstdc++: Build libbacktrace and 19_diagnostics/stacktrace with -funwind-tables [PR111641]
Several of the 19_diagnostics/stacktrace tests FAIL on Solaris/SPARC (32
and 64-bit), Solaris/x86 (32-bit only), and several other targets:
FAIL: 19_diagnostics/stacktrace/current.cc -std=gnu++23 execution test
FAIL: 19_diagnostics/stacktrace/current.cc -std=gnu++26 execution test
FAIL: 19_diagnostics/stacktrace/entry.cc -std=gnu++23 execution test
FAIL: 19_diagnostics/stacktrace/entry.cc -std=gnu++26 execution test
FAIL: 19_diagnostics/stacktrace/output.cc -std=gnu++23 execution test
FAIL: 19_diagnostics/stacktrace/output.cc -std=gnu++26 execution test
FAIL: 19_diagnostics/stacktrace/stacktrace.cc -std=gnu++23 execution test
FAIL: 19_diagnostics/stacktrace/stacktrace.cc -std=gnu++26 execution test
As it turns out, both the copy of libbacktrace in libstdc++ and the
testcases proper need to compiled with -funwind-tables, as is done for
libbacktrace itself.
This isn't an issue on Linux/x86_64 and Solaris/amd64 since 64-bit x86
always defaults to -funwind-tables. 32-bit x86 does, too, when
-fomit-frame-pointer is enabled as on Linux/i686, but unlike
Solaris/i386.
So this patch always enables the option both for the libbacktrace copy
and the testcases.
Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
x86_64-pc-linux-gnu.
