2021-08-20Allow global override of golang GO_DYNLINKOliver Kranz
Small golang applications create massive memory overhead if go-runtime is deployed. So it is helpfull to be able to disable the GO_DYNLINK option on a per distro/local.conf basis by making it a ?= instead of =.

This was added with 98b24e9268 goarch.bbclass: set SECURITY_CFLAGS for mips64 to overcome a problem that was inherent in go linker which has been now fixed in golang compiler upstream https://github.com/golang/go/issues/20243 https://github.com/golang/go/commit/39c07ce9e5311c94880789f19f2f8b49bf1b5241 Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Kai Kang <kai.kang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2019-12-15goarch: Remove target specific dependenciesKhem Raj
goarch is used in all classes of recipes ranging from native to target, therefore its best to contain the variables and not spill over into recipe classes where they can adversely affect shared state reuse e.g. go-native currently gets TUNE_FEATURES into dependency chain of referenced variables which means go-native gets rebuilt when we change from qemuarm to qemux86 machine types since TUNE_FEATURES is defined with DEFAULTTUNE which would change as machines are switched These variables are specific to arm/mips/x86 so marking them with appropriate overrides for native recipes will be right thing here Chose 'hardfloat' for mips which is default too, 7 for arm and sse2 for x86 somehow go-native bootstrap compiler (1.4) still needs them so feed commonly used values or defaults. Fixes ERROR: go-native different signature for task do_configure.sigdata between qemux86copy and qemuarm ... List of dependencies for variable TUNE_FEATURES changed from '{'DEFAULTTUNE', 'TUNE_FEATURES_tune-core2-32'}' to '{'DEFAULTTUNE', 'TUNE_FEATURES_tune-armv7vethf-neon'}' changed items: {'TUNE_FEATURES_tune-core2-32', 'TUNE_FEATURES_tune-armv7vethf-neon'} Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2019-04-10goarch.bbclass: use MACHINEOVERRIDES and simplify go_map_arm()Mark Asselstine
Per https://github.com/golang/go/wiki/GoArm we need to set GOARM when cross building for ARMv5, ARMv6 and ARMv7. The current approach of using TUNE_FEATURES can be error prone, as we can see today when attempting to build for Cortex-A7 which results in GOARM=''. Since the value of MACHINEOVERRIDES already consolidates the values of TUNE_FEATURES into something more consistent we can use the overrides mechanism to set GOARM, leaving just a little bit of logic in go_map_arm() to trigger off the arch (basically target vs host) for the setting of GOARM.

Although RISC-V 64-bit doesn't have official golang support there are forks that now exist with at least some support and work is ongoing in the upstream tree.

2018-03-06goarch.bbclass: disable shared runtime for nativesdk buildsMatt Madison
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.

2017-11-05goarch: There is no GOARCH defined for mips64-n32Joe Slater
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 Barker
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 Madison
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 Madison
* 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.

2017-09-11goarch.bbclass: Replace logic for setting GOARMWill Newton
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.
