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 --- toolchain/Config.in | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'toolchain/Config.in') diff --git a/toolchain/Config.in b/toolchain/Config.in index deff21aa1a..2d7fcc11c8 100644 --- a/toolchain/Config.in +++ b/toolchain/Config.in @@ -212,6 +212,7 @@ comment "C Library" choice prompt "C Library implementation" if TOOLCHAINOPTS default LIBC_USE_GLIBC if mips64 || mips64el + default LIBC_USE_UCLIBC if arc default LIBC_USE_MUSL help Select the C library implementation. @@ -219,6 +220,7 @@ choice config LIBC_USE_GLIBC bool "Use (e)glibc" select USE_GLIBC + depends on !arc config LIBC_USE_UCLIBC select USE_UCLIBC @@ -229,7 +231,7 @@ choice config LIBC_USE_MUSL select USE_MUSL bool "Use musl" - depends on !(mips64 || mips64el) + depends on !(arc || mips64 || mips64el) endchoice @@ -260,17 +262,18 @@ config USE_GLIBC bool config USE_UCLIBC - default y if !TOOLCHAINOPTS && !EXTERNAL_TOOLCHAIN && !NATIVE_TOOLCHAIN && (mips64 || mips64el) + default y if !TOOLCHAINOPTS && !EXTERNAL_TOOLCHAIN && !NATIVE_TOOLCHAIN && (arc || mips64 || mips64el) bool config USE_MUSL - default y if !TOOLCHAINOPTS && !EXTERNAL_TOOLCHAIN && !NATIVE_TOOLCHAIN && !(mips64 || mips64el) + default y if !TOOLCHAINOPTS && !EXTERNAL_TOOLCHAIN && !NATIVE_TOOLCHAIN && !(arc || mips64 || mips64el) bool config USE_EXTERNAL_LIBC bool default y if EXTERNAL_TOOLCHAIN || NATIVE_TOOLCHAIN +source "toolchain/binutils/Config.version" source "toolchain/gcc/Config.version" source "toolchain/glibc/Config.version" -- cgit v1.2.3
