gcc-cross-canadian: Make baremetal specific code generic

2019-04-12T12:40:21+00:00

baremetal override is not valid for cross-canadian anymore therefore use the TARGET_OS overrides Fixes e.g. https://github.com/riscv/meta-riscv/issues/117 (From OE-Core rev: 1bc122a044de280d17525c8e5ee66e81775a7d8b) 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 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: Remove unnecessary --with-mpfr and --with-mpc when cross compiling

2018-10-09T18:04:02+00:00

Passing --with-mpfr and --with-mpc when compiling the cross compiler appears to be at best unnecessary, and at worst can cause build failures. Firstly, the paths passed in gcc-cross-canadian are using the undefined ${layout_exec_prefix}. This results in configure passing -I${STAGING_DIR_HOST}/include twice to the compiler when it's doing its test builds. This is mostly pointless since that directory doesn't exist with the default oe-core configuration - the correct path would be -I${STAGING_DIR_HOST}/usr/include. The path for mpfr passed in gcc-cross is correct, but unnecessary since it is just the sysroot default. I've gone back through the history, and it seems that these lines (or similar ones) were originally added way back in 8800d8be25295dd7c7d84dde62c3be4df8e43346 for GCC 4.1.1 in 2006! I asked[1] if anyone knew why this was necessary but received no response, so I can only assume that no-one knows. I've successfully built for various targets with this patch applied and observed no problems.

gcc: Add missing flex-native dependency

2018-01-13T10:15:19+00:00

This is needed for all stages of the cross/target/canadian compilers and without it (and with indirect gcc dependencies disabled), the steps fail. Add missing dependencies. (From OE-Core rev: e7be4aedd4f1e23c596a8cae0437bc5c187787e5) Signed-off-by: Richard Purdie

gcc-cross-canadian: Use ${target_includedir} for compatibility with meta-micro

2017-06-14T09:18:30+00:00

meta-micro puts headers in /include rather than /usr/include in the sysroot. ${target_includedir} means that the correct path will be used automatically. (From OE-Core rev: 12abcc3791592035d99064262eb3d229fa5ef88c) Signed-off-by: Mike Crowe Acked-by: Phil Blundell Signed-off-by: Richard Purdie

gcc-cross-canadian: Add missing DEPENDS on virtual/${HOST_PREFIX}gcc-crosssdk

2016-01-26T18:05:13+00:00

The cross-canadian compiler needs the nativesdk compiler to build but for some reason this was missing. Add the missing dependency. (From OE-Core rev: 77fcdfdc83f01f1ff0ae310ebb7bffbdb4330156) Signed-off-by: Richard Purdie

meta: Drop now pointless manual -dbg packaging

2015-12-16T11:56:30+00:00

With the autodebug package generation logic, specifically setting FILES_${PN}-dbg isn't needed in most cases, we can remove them. (From OE-Core rev: 3ab59d49dd7c18e194b58d1248b4b87709b5a738) Signed-off-by: Richard Purdie
