goarch.bbclass: Define HOST_GO386 and TARGET_GO386

2017-10-16T22:52:44+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

2017-10-07T22:20:39+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

2017-09-26T10:05:00+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.

goarch.bbclass: set ARM_INSTRUCTION_SET to "arm"

2017-09-14T10:35:45+00:00

Go does not play well with thumb, so ensure that the toolchain and any packages use arm, not thumb, instructions. (From OE-Core rev: 24da8c321831dcc5de00d65d6c5613efee109b57) Signed-off-by: Matt Madison Signed-off-by: Otavio Salvador Signed-off-by: Richard Purdie

goarch.bbclass: identify archs with Go dynamic linking support

2017-09-14T10:35:45+00:00

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.

goarch.bbclass: Add support for ARMv5

2017-09-11T16:30:30+00:00

This adds support to return the proper ARMv5 format. This change is based on the meta-golang[1] layer. Thanks to Matt Madison for his work on this. 1. https://github.com/madisongh/meta-golang (From OE-Core rev: e242e7c3617ded87582c5d384b15027498b0c1a4) Signed-off-by: Otavio Salvador Signed-off-by: Richard Purdie

goarch.bbclass: Replace logic for setting GOARM

2017-09-11T16:30:30+00:00

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.

goarch.bbclass: Stop passing True as second argument of d.getVar

2017-09-11T16:30:30+00:00

The d.getVar has the second argument as True by default, avoid passing it here. (From OE-Core rev: 1a5026db41929d42bece22bd0ae60c13219a98f5) Signed-off-by: Otavio Salvador Signed-off-by: Richard Purdie
