CVS commit: src/external/gpl3/gcc.old/lib/liblto_plugin



Module Name:    src
Committed By:   kamil

Modified Files:
        src/external/gpl3/gcc.old/lib/liblto_plugin: Makefile

Log Message:
Link liblto_plugin with -liberty (gcc.old)

GCC passes liblto_plugin.so in the linker invocation (part of "gcc -v file.c"):

ld -plugin /usr/libexec/liblto_plugin.so -plugin-opt=/usr/libexec/lto-wrapper \
-plugin-opt=-fresolution=/var/tmp//ccxda9Ar.res \
-plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lgcc \
-plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc_s \
-plugin-opt=-pass-through=-lgcc --eh-frame-hdr -dc -dp -e _start \
-dynamic-linker /usr/libexec/ld.elf_so /usr/lib/crt0.o /usr/lib/crti.o \
/usr/lib/crtbegin.o /var/tmp//cc7A7mOK.o --as-needed -lgcc_s --no-as-needed \
-lgcc -lc --as-needed -lgcc_s --no-as-needed -lgcc /usr/lib/crtend.o \
/usr/lib/crtn.o

When attempting to use GNU GOLD, liblto_plugin.so cannot be used because it \
has missing symbol xstrerror:

ld: error: /usr/libexec/liblto_plugin.so: could not load plugin library: \
/usr/libexec/liblto_plugin.so: Undefined PLT symbol "xstrerror" (symnum = 38)

>From Makefiles and sources inspection, liblto_plugin.so shall be linked with \
libiberty (-liberty), a utility GNU library for internal usage with helping \
functions.
