+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/config/bfin: use the generic linker version
+ information
+
+This commit makes the Blackfin platform use the generic linker version
+information, rather than a completely duplicated file, specific for the
+Blackfin architecture.
+
+This is made possible using the newly introduced skip_underscore
+variable of the mkmap-symver script.
+
+This also allows to get a correct linker version file, with symbol names
+matching the ones found in libgcc. Thanks to this, the necessary symbols
+are marked "GLOBAL" instead of "LOCAL", which makes them visible at link
+time, and solves a large number of "undefined reference"
+issues. Indeed, the Blackfin specific linker version script had an extra
+underscore in front of all symbols, which meant none of them matched the
+symbols in libgcc, and therefore all libgcc symbols were marked as
+"LOCAL", making them invisible for linking.

+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.
