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. + +Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> +--- + libgcc/config/bfin/libgcc-glibc.ver | 1894 +---------------------------------- + libgcc/config/bfin/t-linux | 3 +- + 2 files changed, 10 insertions(+), 1893 deletions(-) + +diff --git a/libgcc/config/bfin/libgcc-glibc.ver b/libgcc/config/bfin/libgcc-glibc.ver +index b1bd2df..2af3df7 100644 +--- a/libgcc/config/bfin/libgcc-glibc.ver ++++ b/libgcc/config/bfin/libgcc-glibc.ver +@@ -16,1898 +16,8 @@ + # along with GCC; see the file COPYING3.

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. + +Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> +--- + libgcc/mkmap-symver.awk | 6 +++++- + 1 file changed, 10 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/toolchain/gcc/patches/6.2.0/bfin-workaround.patch b/toolchain/gcc/patches/6.2.0/bfin-workaround.patch deleted file mode 100644 index 7b57a285b..000000000 --- a/toolchain/gcc/patches/6.2.0/bfin-workaround.patch +++ /dev/null @@ -1,15 +0,0 @@ -diff -Nur gcc-6.1.0.orig/libgcc/Makefile.in gcc-6.1.0/libgcc/Makefile.in ---- gcc-6.1.0.orig/libgcc/Makefile.in 2016-02-25 13:23:52.000000000 +0100 -+++ gcc-6.1.0/libgcc/Makefile.in 2016-08-11 21:15:13.841764686 +0200 -@@ -932,7 +932,11 @@ - { $(NM) $(SHLIB_NM_FLAGS) $(libgcc-s-objects); echo %%; \ - cat libgcc.map.in; \ - } | $(AWK) -f $(SHLIB_MKMAP) $(SHLIB_MKMAP_OPTS) > tmp-$@ -+ifeq ($(cpu_type),bfin) -+ sed -e 's/__/_/' tmp-$@ > $@ -+else - mv tmp-$@ $@ -+endif - libgcc_s$(SHLIB_EXT): libgcc.map - mapfile = libgcc.map - endif diff --git a/toolchain/gcc/patches/6.2.0/libgcc_linker-script.patch b/toolchain/gcc/patches/6.2.0/libgcc_linker-script.patch deleted file mode 100644 index 783d15d0a..000000000 --- a/toolchain/gcc/patches/6.2.0/libgcc_linker-script.patch +++ /dev/null @@ -1,16 +0,0 @@ -Solves following linking error: -# bfin-openadk-linux-uclibc-g++ -o foo t.c -bfin-openadk-linux-uclibc/bin/ld: foo: hidden symbol `___udivsi3' in libgcc.a(_udivsi3.o) is referenced by DSO - -diff -Nur gcc-6.1.0.orig/libgcc/config.host gcc-6.1.0/libgcc/config.host ---- gcc-6.1.0.orig/libgcc/config.host 2016-02-26 21:02:28.000000000 +0100 -+++ gcc-6.1.0/libgcc/config.host 2016-07-25 02:47:05.818797217 +0200 -@@ -444,7 +444,7 @@ - md_unwind_header=bfin/linux-unwind.h - ;; - bfin*-linux-uclibc*) -- tmake_file="$tmake_file bfin/t-bfin bfin/t-crtstuff t-libgcc-pic t-fdpbit bfin/t-linux" -+ tmake_file="$tmake_file bfin/t-bfin bfin/t-crtstuff t-libgcc-pic t-slibgcc-libgcc t-fdpbit bfin/t-linux" - # No need to build crtbeginT.o on uClibc systems.
