libgcc/gcc-runtime: Disable thumb mode on armv6

2018-10-17T22:26:52+00:00

Without this the build fails for armv6t targets due to invalid
assembler instructions in thumb mode.

gcc: Remove unnecessary --with-mpfr and --with-mpc when cross compiling

2018-10-09T11:02:41+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: Fix specs generation for ARC

2018-09-22T15:13:14+00:00

GCC's built-in spec for LD is missing a space after
"--eh-frame-hdr" thus with the next option merged together they
are not understood by LD and so LD fails.

Back-port from upstream GCC, see:

gcc: Merge two related patches together

2018-09-05T17:00:00+00:00

These patches may as well be merged together as they affect the same code
and things are clearer this way.

gcc-7.3: Backport fixes for std::pair high memory usage

2018-07-31T21:55:31+00:00

C++ applications that contain a specfic use of std::pair with tempates
cause the build to require many gigabytes of RAM to build.

This is a fix that was applied to the upstream GCC 7 branch.
