gcc: Configure all gccs with --disable-install-libiberty

2020-04-26T13:00:50+00:00

OE uses libiberty from binutils, since its properly compiled as pic archive and applications and other libraries needing libiberty can properly link with it. With this option applied, explicit delete of libiberty headers and libraries is not required in install step, since they wont get installed in first place.

gcc-cross.inc: Remove test runner script generation

2019-12-06T14:41:28+00:00

Remove the generation of the testgcc script which could be used to run the gcc test suite against a cross compiler with a remote execution target. The same functionality can now be achieved with the 'do_check' task of gcc-runtime or with oe-selftest (for automation of execution against qemu-user/qemu-system targets).

gcc: Improve build reproduciblity

2019-12-06T14:41:28+00:00

Prevent the gcc embedded checksum from containing a checksum that was computed with build specific paths. The checksum-options file included the value of LINKER/LDFLAGS which contains DEBUG_PREFIX_MAP and STAGING_DIR_TARGET.

gcc-cross.inc: Prevent native sysroot from leaking into configargs.h

2019-11-29T17:43:40+00:00

Prevent the native(sdk) sysroot path from leaking into configargs.h. The configargs.h header is intended to be static and unchanged as the content is used as a means of determining that a gcc plugin is built for the same gcc. This also effects the output of 'gcc --version'. Due to per recipe sysroots and staging, the sysroot path would be replaced with the sysroot local to the recipe thus changing the content of configargs.h. The sysroot path is replaced with a generic "/host" prefix which represents the host sysroot (e.g. native or nativesdk).

gcc-cross.inc: Process binaries in build dir to be relocatable

2019-09-16T22:02:43+00:00

Process binaries within the build directory before stashing to be relocatable with ORIGIN relative rpaths. This corrects issues with rpaths being invalid when trying to use the binaries from an unstashed build directory (e.g. gcc-runtime).

gcc-cross: Fix header file corruption problems

2019-09-06T07:24:41+00:00

gcc's makefile can move files, replacing with the contents "timestamp". This corrupts the headers and breaks things like the gcc testsuite. Add in a fix to ensure the headers are not corrupted through their hardlink copies. (From OE-Core rev: 7e75ed5aec86b94fe7fadbed606619f84a2e58e7) Signed-off-by: Richard Purdie

gcc-cross: Clean up fixed-includes

2019-09-01T21:33:07+00:00

We had interesting failures where building gcc-cross-powerpc with 5.0 kernel headers, then building eudev after moving to 5.2 headers failed. gcc-cross doesn't rebuild when linux-libc-headers changes due to its listing in SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS. This shouldn't matter but fixincludes as adding asm-generic/socket.h to its filtered list which was then replacing the real header with an older version. This mismatch lead to build failures. We trust the Linux kernel headers to be ANSI safe so lets just clear out any headers and trust the originals to be correct.

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.
