From 1c93a8353d0b641a6fa0077e81ecc8dd3efcae56 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 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@47438 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- toolchain/uClibc/common.mk | 1 + toolchain/uClibc/config/arc | 10 ++++++++++ 2 files changed, 11 insertions(+) create mode 100644 toolchain/uClibc/config/arc (limited to 'toolchain/uClibc') diff --git a/toolchain/uClibc/common.mk b/toolchain/uClibc/common.mk index 895022ce60..3d0a501247 100644 --- a/toolchain/uClibc/common.mk +++ b/toolchain/uClibc/common.mk @@ -23,6 +23,7 @@ HOST_BUILD_DIR:=$(BUILD_DIR_TOOLCHAIN)/$(PKG_NAME)-$(PKG_VERSION) include $(INCLUDE_DIR)/toolchain-build.mk UCLIBC_TARGET_ARCH:=$(shell echo $(ARCH) | sed -e s'/-.*//' \ + -e 's/arc.*/arc/' \ -e 's/i.86/i386/' \ -e 's/sparc.*/sparc/' \ -e 's/arm.*/arm/g' \ diff --git a/toolchain/uClibc/config/arc b/toolchain/uClibc/config/arc new file mode 100644 index 0000000000..de1ffc4415 --- /dev/null +++ b/toolchain/uClibc/config/arc @@ -0,0 +1,10 @@ +ARCH_ANY_ENDIAN=y +ARCH_LITTLE_ENDIAN=y +ARCH_WANTS_LITTLE_ENDIAN=y +TARGET_ARCH="arc" +TARGET_arc=y +CONFIG_ARC_CPU_700=y +# CONFIG_ARC_CPU_HS is not set +CONFIG_ARC_PAGE_SIZE_8K=y +# CONFIG_ARC_PAGE_SIZE_16K is not set +# CONFIG_ARC_PAGE_SIZE_4K is not set -- cgit v1.2.3
