2023-08-11config: Fix host -rdynamic detection for build != host != targetJoseph Myers1-1/+1
The GCC_ENABLE_PLUGINS configure logic for detecting whether -rdynamic is necessary and supported uses an appropriate objdump for $host binaries (running on $build) in cases where $host is $build or $target. However, it is missing such logic in the case where $host is neither $build nor $target, resulting in the compilers not being linked with -rdynamic and plugins not being usable with such a compiler. In fact $ac_cv_prog_OBJDUMP, as used when $build = $host, is always an objdump for $host binaries that runs on $build; that is, it's appropriate to use in this case as well. Tested in such a configuration that it does result in cc1 being linked with -rdynamic as expected. Also bootstrapped with no regressions for x86_64-pc-linux-gnu. config/ * gcc-plugin.m4 (GCC_ENABLE_PLUGINS): Use export_sym_check="$ac_cv_prog_OBJDUMP -T" also when host is not build or target. gcc/ * configure: Regenerate. libcc1/ * configure: Regenerate.
