This call updates the value of the +xtensa_current_frame_size static variable, used in "return" instruction +predicate. Prior to the change the value of xtensa_current_frame_size was +set to 0 after the end of epilogue generation, which enabled the "return" +instruction for the CALL0 ABI, but after the change the additional +INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero +and "return" pattern unavailable. + +Get rid of the global xtensa_current_frame_size and +xtensa_callee_save_size variables by moving them into the +machine_function structure.

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. + +Signed-off-by: Thomas Petazzoni +--- + libgcc/mkmap-symver.awk | 6 +++++- + 1 file changed, 5 insertions(+), 1 deletion(-) + +diff --git a/libgcc/mkmap-symver.awk b/libgcc/mkmap-symver.awk +index 266832a..30bb179 100644 +--- a/libgcc/mkmap-symver.awk ++++ b/libgcc/mkmap-symver.awk +@@ -47,7 +47,11 @@ state == "nm" && ($1 == "U" || $2 == "U") { + + state == "nm" && NF == 3 { + split ($3, s, "@") +- def[s[1]] = 1; ++ if (skip_underscore) ++ symname = substr(s[1], 2); ++ else ++ symname = s[1]; ++ def[symname] = 1; + sawsymbol = 1; + next; + } +-- +2.7.4 + diff --git a/patches/gcc/linaro-6.3-2017.02/893-libgcc-config-bfin-use-the-generic-linker-version-in.patch b/patches/gcc/linaro-6.3-2017.02/893-libgcc-config-bfin-use-the-generic-linker-version-in.patch new file mode 100644 index 00000000..454295d0 --- /dev/null +++ b/patches/gcc/linaro-6.3-2017.02/893-libgcc-config-bfin-use-the-generic-linker-version-in.patch @@ -0,0 +1,1944 @@ +From 56d606931716de30a89a40dc69a9282c1b4e2880 Mon Sep 17 00:00:00 2001 +From: Thomas Petazzoni +Date: Thu, 18 Aug 2016 18:04:06 +0200 +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.
