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.

Subject: [PATCH] libgcc: fix DWARF compilation with FDPIC targets
|
||||
|
||||
The build of unwind-dw2-fde-dip.c currently fails for FDPIC targets with
|
||||
the following error:
|
||||
|
||||
libgcc/unwind-dw2-fde-dip.c:167:31: error: storage size of 'load_base' isn't known
|
||||
struct elf32_fdpic_loadaddr load_base;
|
||||
|
||||
This patch addresses that by defining load_base with the appropriate
|
||||
type on FDPIC targets. It has been tested on FRV and Blackfin.
|
||||
|
||||
Fixes PR gcc/68468.
