MIPS: rename M5101 core to M5150

2016-11-09T21:41:51+00:00

m5101 is the -march option for GCC, but the real core name is M5150. Signed-off-by: Vicente Olivert Riera Reviewed-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

arch/Config.in.mips: add support for XBurst cores

2016-11-09T20:36:34+00:00

The Ingenic XBurst is a MIPS32R2 microprocessor. It has a bug in the FPU that can generate incorrect results in certain cases. The problem shows up when you have several fused madd instructions in sequence with dependant operands. Using the -mno-fused-madd option prevents gcc from emitting these instructions. This patch adds changes to the toolchain wrapper to use that option. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

toolchain-external.mk: fix ARCH_SUBDIR calculation

2016-10-28T12:28:49+00:00

ARCH_SUBDIR is computed based on the value of ARCH_SYSROOT_DIR and SYSROOT_DIR. For nested toolchains ARCH_SYSROOT_DIR is a subdir of SYSROOT_DIR, so a sed command like this one... sed -r -e "s:^${SYSROOT_DIR}(.*)/$:\1:" ...basically removes the leading SYSROOT_DIR part from ARCH_SYSROOT_DIR. But, for side-by-side sysroot toolchains ARCH_SYSROOT_DIR and SYSROOT_DIR are at the same level, so the above sed command doesn't make any effect. This patch therefore improves the calculation of ARCH_SUBDIR to clearly handle the three possible cases: - There is a single sysroot, or the selected architecture sysroot is the main one (i.e SYSROOT_DIR == ARCH_SYSROOT_DIR). In this case, ARCH_SUBDIR is empty. - There are side-by-side sysroots, such as SYSROOT_DIR=.../sysroot/mips-r2-hard/ and ARCH_SYSROOT_DIR=.../sysroot/mipsel-r2-hard/. - The arch-sysroot is nested, such as SYSROOT_DIR=.../sysroot and ARCH_SYSROOT_DIR=.../sysroot/armv4t/ Signed-off-by: Vicente Olivert Riera [Thomas: improve the logic to handle the SYSROOT_DIR==ARCH_SYSROOT_DIR case.] Signed-off-by: Thomas Petazzoni

toolchain-external: install libmvec.so from glibc toolchains

2016-10-27T08:41:44+00:00

On some architectures (namely x86-64), glibc may provide a libmvec library since glibc 2.22, which programs built with gcc OpenMP support might get linked to. In order for these programs to work on the target, we need to copy this library to the target filesystem. This commit takes care of this for the external toolchain situation. Note that libraries listed in TOOLCHAIN_EXTERNAL_LIBS are silently ignored if they don't exist. Therefore, we don't need to have any condition on the architecture or glibc version. For more details on libmvec, see https://sourceware.org/glibc/wiki/libmvec. Fixes bug #9111. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

toolchain: configs: improve toolchain config readability

2016-10-25T21:31:47+00:00

Add (or move) comment lines in toolchain-related Config.in files to improve readability of the toolchain config section. Source linux-headers/Config.in.host after toolchain-buildroot items. For toolchain-buildroot case, the config file now looks like this: * * Toolchain * * * Toolchain Buildroot Options * * * Kernel Header Options * * * uClibc Options * * * Binutils Options * * * GCC Options * * * Host GDB Options * * * Toolchain Generic Options * Signed-off-by: Petri Gynther Signed-off-by: Thomas Petazzoni
