The build system implementation of multilib layout is very generic and allows +complete customisation of the library directories. + +This patch is a partial solution to allow any custom directories to be passed into gcc +and handled correctly. It forces gcc to use the base_libdir (which is the current +directory, "."). We need to do this for each multilib that is configured as we don't +know which compiler options may be being passed into the compiler. Since we have a compiler +per mulitlib at this point that isn't an issue. + +The one problem is the target compiler is only going to work for the default multlilib at +this point. Ideally we'd figure out which multilibs were being enabled with which paths +and be able to patch these entries with a complete set of correct paths but this we +don't have such code at this point. This is something the target gcc recipe should do +and override these platform defaults in its build config. + +Do same for riscv64 and aarch64 + +RP 15/8/11 + +Upstream-Status: Inappropriate[OE-Specific] + +Signed-off-by: Khem Raj <raj.khem@gmail.com> +Signed-off-by: Elvis Dowson <elvis.dowson@gmail.com> +Signed-off-by: Mark Hatle <mark.hatle@windriver.com> +Signed-off-by: Mark Hatle <mark.hatle@xilinx.com> + +Index: gcc-9.2.0/gcc/config/microblaze/t-microblaze +=================================================================== +--- gcc-9.2.0.orig/gcc/config/microblaze/t-microblaze ++++ gcc-9.2.0/gcc/config/microblaze/t-microblaze +@@ -1,5 +1,6 @@ + MULTILIB_OPTIONS = m64 mxl-barrel-shift mlittle-endian mno-xl-soft-mul mxl-multiply-high +-MULTILIB_DIRNAMES = m64 bs le m mh ++#MULTILIB_DIRNAMES = m64 bs le m mh ++MULTILIB_DIRNAMES = . . . . . + MULTILIB_EXCEPTIONS = *m64/mxl-multiply-high mxl-multiply-high + MULTILIB_EXCEPTIONS += *m64 + MULTILIB_EXCEPTIONS += *m64/mxl-barrel-shift +Index: gcc-9.2.0/gcc/config/microblaze/t-microblaze-linux +=================================================================== +--- gcc-9.2.0.orig/gcc/config/microblaze/t-microblaze-linux ++++ gcc-9.2.0/gcc/config/microblaze/t-microblaze-linux +@@ -1,3 +1,4 @@ + MULTILIB_OPTIONS = mxl-barrel-shift mno-xl-soft-mul mxl-multiply-high +-MULTILIB_DIRNAMES = bs m mh ++#MULTILIB_DIRNAMES = bs m mh ++MULTILIB_DIRNAMES = . . . + MULTILIB_EXCEPTIONS = *mxl-barrel-shift/mxl-multiply-high mxl-multiply-high |
