gcc-runtime: Add --cache-file to EXTRA_OECONF

2019-01-24T17:45:25+00:00

This can save configure time since it runs configure multiple times: $ time bitbake gcc-runtime -cconfigure 60s -> 54s Saved 6s (From OE-Core rev: 48cc7179ffeb89adf1ba5212338b958684e43962) Signed-off-by: Robert Yang Signed-off-by: Richard Purdie

gcc: Fix riscv multilibs for OE way

2019-01-03T12:35:53+00:00

In OE we do not build mutlib like gcc does it by default, this ensures that mutlilib is virtually disabled for OE, since we hardly use same gcc to build for multiple ABIs This fixes cases in SDK where g++ is not able to find standard c++ include headers (From OE-Core rev: badbeb01dd642d9d647d3760a3ce2aa39c3567da) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

recipes: Drop virtual/libc-for-gcc

2018-12-26T11:19:54+00:00

We no longer have special "libc" for gcc so we can rely on plain virtual/libc and reduce the complexity in the dependencies. (From OE-Core rev: 122217b421f749b5fef52bea44ad6e04bc8f8d3a) Signed-off-by: Richard Purdie

gcc: Drop the -initial versions of the compiler

2018-12-26T11:19:54+00:00

Separated out from the previous commit for clarity, this simply drops all the -inital pieces of gcc which are no longer needed after the previous commit. (From OE-Core rev: d84971928b68efddbdb6344b1021d998c9e26adb) Signed-off-by: Richard Purdie

gcc: Drop gcc-cross-initial and use gcc-cross instead

2018-12-26T11:19:54+00:00

We need a libgcc to build glibc. Tranditionally we therefore build a non-threaded and non-shared compiler (gcc-cross-initial), then use that to build libgcc-initial which is used to build glibc which we can then build gcc-cross and libgcc against. Firstly, we can drop the glibc dependency from gcc-cross, *if* we make two changes: a) specify the minimum glibc version to support in a configure option b) create a dummy limits.h file so that later when glibc creates one, the headers structure has support for it. We can do this with a simple empty file Once gcc-cross is libc independent, we can use it to build both libgcc-initial and then later libgcc. libgcc-initial is tricky as we need to imitate the non-threaded and non-shared case. We can do that by hacking the threading mode back to "single" even if gcc reports "posix" and disable libc presence for the libgcc-intial build. We have to create the dummy limits.h to avoid compiler errors from a missing header. glibc will fail to link with libgcc-initial due to a missing "exception handler" capable libgcc (libgcc_eh.a). Since we know glibc doesn't need any exception handler, we can safely symlink to libgcc.a. With those changes, gcc-cross can be used in all places and we only need one build of gcc for each architecture. For some reason ifunc was being disabled on mips prior to these changes but afterwards became enabled but caused assertion failures. This is therefore disabled until we can debug that.

gcc-runtime: Drop building libmpx

2018-12-20T14:53:55+00:00

libmpx is not supported any longer and infact has been removed completely from gcc-9, see https://github.com/gcc-mirror/gcc/commit/1e42d5c637e1b1f65dfddd0923dfb25676bb56e5 (From OE-Core rev: 547174fc834273af67a2f7e50a3cf6c8e3b900f4) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

gcc-runtime: Add missing libc dependency

2018-12-18T16:19:34+00:00

For reasons lost in the depths of time, perhaps performane related, we only have a dependency on libc at packaging time. This is too late, as demonstrated by a recent build failure on non-IA builds where the glibc 2.29 upgrade had been removed from the build: ld: recipe-sysroot/usr/lib/../lib/libstdc++.so: undefined reference to `log@GLIBC_2.29' libstdc++ should have been rebuilt but had not as the dependency wasn't present. Add the missing dependency to avoid this problem (and drop the other form of dependency which is no longer needed).

gcc: Drop 7.3 since 8.2 is working fine for us

2018-12-15T17:10:52+00:00

We've had gcc 8.2 around for long enough that 7.3 can be removed now. (From OE-Core rev: 20aea61385e1a53ac245353899277ba20104ed2f) Signed-off-by: Richard Purdie
