-Subject: [PATCH] [Patch, microblaze]: Enable DWARF exception handling support.
-
-Changelog
-
-2013-03-18  Edgar E. Iglesias <edgar.iglesias@xilinx.com>
-            David Holsgrove <david.holsgrove@xilinx.com>

- * config/microblaze/microblaze-protos.h: Add
-   microblaze_eh_return prototype.
- * gcc/config/microblaze/microblaze.c: (microblaze_must_save_register,
-   microblaze_expand_epilogue, microblaze_return_addr): Handle
-   calls_eh_return
-   (microblaze_eh_return): New function.
- * gcc/config/microblaze/microblaze.h: Define RETURN_ADDR_OFFSET,
-   EH_RETURN_DATA_REGNO, MB_EH_STACKADJ_REGNUM, EH_RETURN_STACKADJ_RTX,
-   ASM_PREFERRED_EH_DATA_FORMAT
- * gcc/config/microblaze/microblaze.md: Define eh_return pattern.

-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.
-

-From ae9c3e354440c4a0f105a9eabfb2f77be085ebc1 Mon Sep 17 00:00:00 2001
-From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

-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.
