From 8b5d644bb36846660e1fa20d38361fec12a14b28 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 10 Nov 2015 12:03:59 +0000 Subject: toolchain: add support of ARC architecture This includes binutils, gcc, gdb and uClibc-ng. Latest release of ARC gcc (as of today it is "arc-2015.06") is based on upstream gcc 4.8.4. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/gcc Latest release of ARC binutils (as of today it is "arc-2015.06") is based on upstream binutils 2.23. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06 Latest release of ARC GDB (as of today this is "arc-2015.06-gdb") is based on upstream gdb 7.9.1. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb Note that for binutils and gdb that come from unified git repository (which is the case for upstream binutils/gdb today) we need to disable building of gdb in binutils and binutils in gdb hence in binutils: ------>8------ --disable-sim --disable-gdb ------>8------ and in gdb: ------>8------ --disable-binutils --disable-ld --disable-gas ------>8------ Also in gdb we disable sim because if the following breakage while building with it: ------------>8------------ /usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \ -mono -fast -pbb -switch sem5-switch.c \ -cpu a5f -infile ./mloop5.in \ -outfile-suffix 5 unknown option: bash Makefile:699: recipe for target 'stamp-5mloop' failed make[7]: *** [stamp-5mloop] Error 1 ------------>8------------ Cc: Felix Fietkau Cc: John Crispin Cc: Jonas Gorski Signed-off-by: Alexey Brodkin SVN-Revision: 47438 --- include/target.mk | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/target.mk') diff --git a/include/target.mk b/include/target.mk index 798805604c..102b3a0d35 100644 --- a/include/target.mk +++ b/include/target.mk @@ -260,6 +260,10 @@ ifeq ($(DUMP),1) CPU_TYPE ?= armv8-a CPU_CFLAGS_armv8-a = -mcpu=armv8-a endif + ifeq ($(ARCH),arc) + CPU_TYPE ?= arc700 + CPU_CFLAGS_arc700 = -marc700 + endif DEFAULT_CFLAGS=$(strip $(CPU_CFLAGS) $(CPU_CFLAGS_$(CPU_TYPE)) $(CPU_CFLAGS_$(CPU_SUBTYPE))) endif -- cgit v1.2.3
