-Subject: [PATCH] libgcc/mkmap-symver: support skip_underscore
-
-Some platforms, such as Blackfin, have a special prefix for assembly
-symbols as opposed to C symbols. For this reason, a function named
-"foo()" in C will in fact be visible as a symbol called "_foo" in the
-ELF binary.
-
-The current linker version script logic in libgcc doesn't take into
-account this situation properly. The Blackfin specific
-libgcc/config/bfin/libgcc-glibc.ver has an additional "_" in front of
-every symbol so that it matches the output of "nm" (which gets parsed to
-produce the final linker version script). But due to this additional
-"_", ld no longer matches with the symbols since "ld" does the matching
-with the original symbol name, not the one prefixed with "_".
-
-Due to this, none of the symbols in libgcc/config/bfin/libgcc-glibc.ver
-are actually matched with symbols in libgcc. This causes all libgcc
-symbols to be left as "LOCAL", which causes lots of "undefined
-reference" whenever some C or C++ code that calls a function of libgcc
-is compiled.
-
-To address this, this commit introduces a "skip_underscore" variable to
-the mkmap-symver script. It tells mkmap-symver to ignore the leading
-underscore from the "nm" output.
-
-Note that this new argument is different from the existing
-"leading_underscore" argument, which *adds* an additional underscore to
-the generated linker version script.
-
-Having this functionality paves the way to using the generic linker
-version information for Blackfin, instead of using a custom one.
