2018-07-18recipes: Enforce ARM ISA just for arm arches <= armv5Khem Raj1
armv7+ used thumb2 ISA and it compiles fine with thumb2 issues are only when using thumb1 ISA Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2018-06-15goarch.bbclass: set SECURITY_CFLAGS for mips64Kai Kang1
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.

2018-03-06go.bbclass, goarch.bbclass: update SECURITY_CFLAGSMatt Madison1
With go1.10 the NOPIE flags are only required for MIPS target builds, and are now incompatible for the other architectures. Signed-off-by: Matt Madison <matt@madison.systems> Signed-off-by: Ross Burton <ross.burton@intel.com>
2018-03-06goarch.bbclass: disable shared runtime for nativesdk buildsMatt Madison1
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.

2018-03-06go: set GOMIPS envrionment variableMatt Madison1
Go 1.10 adds support for selecting hard/soft float object code through the GOMIPS environment variable. Signed-off-by: Matt Madison <matt@madison.systems> Signed-off-by: Ross Burton <ross.burton@intel.com>
2018-01-25classes/recipes: Convert SkipPackage -> SkipRecipeRichard Purdie1
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. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2017-11-05goarch: There is no GOARCH defined for mips64-n32Joe Slater1
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. Signed-off-by: Joe Slater <jslater@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
2017-10-16goarch.bbclass: Define HOST_GO386 and TARGET_GO386Paul Barker1
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.

2017-10-06goarch.bbclass: rework mips architecture checksMatt Madison1
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.

2017-09-25goarch.bbclass: fixups for Go mips32 supportMatt Madison1
* 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.

2017-09-13goarch.bbclass: set ARM_INSTRUCTION_SET to "arm"Matt Madison1
Go does not play well with thumb, so ensure that the toolchain and any packages use arm, not thumb, instructions. Signed-off-by: Matt Madison <matt@madison.systems> Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2017-09-13goarch.bbclass: identify archs with Go dynamic linking supportMatt Madison1
Go only supports shared libraries for some architectures, so add a variable for use elsewhere that gets a non-null value only for those architectures.

2017-09-11goarch.bbclass: Add support for ARMv5Otavio Salvador1
This adds support to return the proper ARMv5 format. This change is based on the meta-golang[1] layer. Thanks to Matt Madison <matt@madison.systems> for his work on this. 1. https://github.com/madisongh/meta-golang Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2017-09-11goarch.bbclass: Replace logic for setting GOARMWill Newton1
The previous logic applied a regex to TUNE_FEATURES which could set the GOARM value to 7 incorrectly, for example when dealing with an arm1176 core. Simplify to check for the presence of "armv7" instead. At the same time add a check for "armv6" and set GOARM to 6 in that case.
