arch/mips: add option for toolchains supporting -mfpxx

2017-07-21T20:49:18+00:00

-mfpxx option was added in gcc-5.1.0 so make sure that users cannot select the "xx" fp32 mode when using toolchains that have a gcc older than 5.1.0. -mfp32 and -mfp64 were added in gcc-4.1.0, so given the older gcc version we support in Buildroot (in the GCC_AT_LEAST options) is 4.3 we don't need to do anything else for them.

arch/mips: add option for toolchains supporting -mnan

2017-07-21T20:48:51+00:00

-mnan option was added in gcc-4.9.0 so make sure that users cannot select the NaN mode when using toolchains that have a gcc older than 4.9.0, and also make sure that the -mnan option is not passed at all to the toolchain-wrapper and target cflags.

arch/mips: add support for MIPS32 FP mode

2017-07-16T14:45:22+00:00

MIPS32 support different FP modes (32,xx,64), so give the user the opportunity to choose between them. That will cause host-gcc to be built using the --with-fp-32=[32|xx|64] configure option. Also the -mfp[32|xx|64] gcc option will be added to TARGET_CFLAGS and to the toolchain wrapper. FP mode option shouldn't be used for soft-float, so we add logic in the toolchain wrapper if -msoft-float is among the arguments in order to not append the -fp[[32|xx|64] option, otherwise the compilation may fail. Information about FP modes here: - https://sourceware.org/binutils/docs/as/MIPS-Options.html - https://dmz-portal.imgtec.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking#5._Generating_modeless_code Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

arch/mips: add support for MIPS NaN

2017-07-16T14:35:39+00:00

MIPS supports two different NaN encodings, legacy and 2008. Information about MIPS NaN encodings can be found here: https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html NaN legacy is the only option available for R2 cores and older. NaN 2008 is the only option available for R6 cores. R5 cores can have either NaN legacy or NaN 2008, depending on the implementation. So, if the user selects a generic R5 target architecture variant, we show a choice menu with both options available. For well known R5 cores we directly select the NaN enconding they use.

arch, linux, package: remove whitespaces

2017-03-29T21:30:37+00:00

Whitespaces were searched using the following regex: [ ]{1,}\t and then manually removed in most of the cases. For xserver_xorg-server.mk, tabs before backslashes were removed. Signed-off-by: Bernd Kuhls Signed-off-by: Thomas Petazzoni

arch: add BR2_READELF_ARCH_NAME hidden config option

2017-03-20T21:22:17+00:00

This config option corresponds to the string returned by readelf for the "Machine" field of the ELF header. It will be used to check if the architecture of binaries built by Buildroot match the target architecture. Signed-off-by: Thomas Petazzoni

MIPS: rename M6201 core to M6250
