We use +these directories so that multiple gcc versions could in theory +co-exist on target. + +We only want to build one gcc-cross-canadian per arch and have this work +for all multilibs. <target-sys> can be handled by mapping the multilib +<target-sys> to the one used by gcc-cross-canadian, e.g. +mips64-polkmllib32-linux +is symlinked to by mips64-poky-linux. + +The default gcc search path in the target sysroot for a "lib64" mutlilib +is: + +<sysroot>/lib32/mips64-poky-linux/5.2.0/ +<sysroot>/lib32/../lib64/ +<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/ +<sysroot>/usr/lib32/../lib64/ +<sysroot>/lib32/ +<sysroot>/usr/lib32/ + +which means that the lib32 crtbegin.o will be found and the lib64 ones +will not which leads to compiler failures. + +This patch injects a multilib version of that path first so the lib64 +binaries can be found first. With this change the search path becomes: + +<sysroot>/lib32/../lib64/mips64-poky-linux/5.2.0/ +<sysroot>/lib32/mips64-poky-linux/5.2.0/ +<sysroot>/lib32/../lib64/ +<sysroot>/usr/lib32/../lib64/mips64-poky-linux/5.2.0/ +<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/ +<sysroot>/usr/lib32/../lib64/ +<sysroot>/lib32/ +<sysroot>/usr/lib32/ + +Upstream-Status: Pending +RP 2015/7/31 + +Signed-off-by: Khem Raj <raj.khem@gmail.com> +--- + gcc/gcc.c | 29 ++++++++++++++++++++++++++++- + 1 file changed, 28 insertions(+), 1 deletion(-) + +diff --git a/gcc/gcc.c b/gcc/gcc.c +index e015c77f15f..84af5d5a2e1 100644 +--- a/gcc/gcc.c ++++ b/gcc/gcc.c +@@ -2533,7 +2533,7 @@ for_each_path (const struct path_prefix *paths, + if (path == NULL) + { + len = paths->max_len + extra_space + 1; +- len += MAX (MAX (suffix_len, multi_os_dir_len), multiarch_len); ++ len += MAX ((suffix_len + multi_os_dir_len), multiarch_len); + path = XNEWVEC (char, len); + } + +@@ -2545,6 +2545,33 @@ for_each_path (const struct path_prefix *paths, + /* Look first in MACHINE/VERSION subdirectory. */ + if (!skip_multi_dir) + { ++ if (!(pl->os_multilib ? skip_multi_os_dir : skip_multi_dir)) ++ { ++ const char *this_multi; ++ size_t this_multi_len; ++ ++ if (pl->os_multilib) ++ { ++ this_multi = multi_os_dir; ++ this_multi_len = multi_os_dir_len; ++ } ++ else ++ { ++ this_multi = multi_dir; ++ this_multi_len = multi_dir_len; ++ } ++ ++ /* Look in multilib MACHINE/VERSION subdirectory first */ ++ if (this_multi_len) ++ { ++ memcpy (path + len, this_multi, this_multi_len + 1); ++ memcpy (path + len + this_multi_len, multi_suffix, suffix_len + 1); ++ ret = callback (path, callback_info); ++ if (ret) ++ break; ++ } ++ } ++ + memcpy (path + len, multi_suffix, suffix_len + 1); + ret = callback (path, callback_info); + if (ret) +-- +2.12.2 + |
