From 4d9bc81a5d8d884dee7a7781fa4c1577a6c9681a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 11 Aug 2023 13:20:07 +0000 Subject: config: Fix host -rdynamic detection for build != host != target 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. --- libcc1/configure | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'libcc1') diff --git a/libcc1/configure b/libcc1/configure index 1a63a0e..2a914a0 100755 --- a/libcc1/configure +++ b/libcc1/configure @@ -15120,7 +15120,7 @@ fi elif test x$host = x$target; then export_sym_check="$gcc_cv_objdump -T" else - export_sym_check= + export_sym_check="$ac_cv_prog_OBJDUMP -T" fi ;; esac -- cgit v1.1
