recipes: Enforce ARM ISA just for arm arches <= armv5

2018-07-18T09:13:30+00:00

armv7+ used thumb2 ISA and it compiles fine with thumb2
issues are only when using thumb1 ISA

goarch.bbclass: set SECURITY_CFLAGS for mips64

2018-06-15T10:12:34+00:00

When include conf/distro/include/security_flags.inc, NOPIE flags are
still required for mips64 target builds. Otherwise it fails to build
packages such as glide which inherit go.bbclass:

| .../tmp-glibc/work/mips64-wrs-linux/glide/0.13.1-r0/recipe-sysroot-native/usr/bin/mips64-wrs-linux/../../libexec/mips64-wrs-linux/
| gcc/mips64-wrs-linux/7.3.0/ld: .../tmp-glibc/work/mips64-wrs-linux/glide/0.13.1-r0/go-tmp/go-link-518447869/go.o:
| relocation r_mips_26 against `a local symbol' can not be used when making a shared object; recompile with -fPIC`

Use override 'mipsarch' to set SECURITY_CFLAGS for both mips and mips64.

go.bbclass, goarch.bbclass: update SECURITY_CFLAGS

2018-03-06T14:36:33+00:00

With go1.10 the NOPIE flags are only required for
MIPS target builds, and are now incompatible for
the other architectures.

goarch.bbclass: disable shared runtime for nativesdk builds

2018-03-06T14:36:33+00:00

While useful on embedded devices for saving disk space, use
of shared runtime in Go is not the usual practice, so disable
it for nativesdk builds.  We don't use it for native builds,
either, so this makes the SDK match the native environment
more closely.

go: set GOMIPS envrionment variable

2018-03-06T14:36:32+00:00

Go 1.10 adds support for selecting hard/soft float
object code through the GOMIPS environment variable.

classes/recipes: Convert SkipPackage -> SkipRecipe

2018-01-25T11:31:16+00:00

The new name is much more consistent with what this actually means. We put
the pieces in place to rename everything a while back but looks like we
forgot to actually do it! Fix that now.

goarch: There is no GOARCH defined for mips64-n32

2017-11-05T13:54:45+00:00

Defeat building for mipsarchn32 because there is no corresponding
GOARCH.  Neither "mips" nor "mips64" allows go-runtime to compile.
Existing mips32 code assumes the o32 ABI.

goarch.bbclass: Define HOST_GO386 and TARGET_GO386

2017-10-16T22:52:04+00:00

These variables are used to control the floating-point instructions emitted by
the go compiler for x86 architectures.

The default is '387' which disables the use of sse/sse2 instructions and is safe
to use on all x86 processors from the i486 onwards.

If TUNE_FEATURES contains a feature set which is known to support sse/sse2
instructions then they are set to 'sse2' to enable the use of these
instructions. This is suitable for most processors from Pentium 4 onwards.

Only the 'core2' and 'corei7' TUNE_FEATURES are defined in the oe-core layer and
are known to support ss2 instructions. Other layers may introduce additional
tunings which support sse2 instructions and for these layers, TARGET_GO386
or go_map_386 should be overridden as needed.

goarch.bbclass: rework mips architecture checks

2017-10-06T11:03:32+00:00

Remove the TUNE_FEATURES references from go_map_arch,
to avoid an unwanted variable dependency.  Direct
comparisons of the architecture name are sufficient
for covering what Go currently supports, and using
TUNE_CCARGS_remove adequately handles the conflict
with the cgo-supplied flags for mips.

goarch.bbclass: fixups for Go mips32 support

2017-09-25T13:17:42+00:00

* Fix the regular expression in the mips test

* Flag as incompatible any mips32 tunes for n32 ABI
  or soft-float, as go does not support them.

* Replace mips32r2 tune with mips32r1. Go only supports
  mips32r1, which is a strict subset of r2.  Adjusting
  this tune is not ideal, but is hopefully a temporary
  measure until more complete mips32 ISA coverage
  arrives upstream.
