As of today gdb port for ARC is not yet in upstream even though we're working hard on that.
Still to allow ARC users to debug user-space apps on top of Linux kernel we're adding here support for building GDB from sources hosted on our GitHub here: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2016.03-gdb Likewise for host GDB sources that come from unified git repository (which is the case for upstream binutils/gdb today) we need to disable building of binutils in gdb: ------>8------ --disable-binutils --disable-ld --disable-gas ------>8------ Also 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------------ Signed-off-by: Alexey Brodkin <abrod...@synopsys.com> Cc: John Crispin <j...@phrozen.org> Cc: Felix Fietkau <n...@nbd.name> --- package/devel/gdb/Makefile | 23 ++++++++++++++-- .../001-gdb-pr14523-mips-signal-number.patch | 0 .../gdb/patches/{ => 7.11}/100-musl_fix.patch | 0 .../patches/arc-2016.03/100-no_extern_inline.patch | 32 ++++++++++++++++++++++ .../gdb/patches/arc-2016.03/110-no_testsuite.patch | 21 ++++++++++++++ .../120-fix-compile-flag-mismatch.patch | 11 ++++++++ .../arc-2016.03/200-arc-fix-target-mask.patch | 13 +++++++++ 7 files changed, 98 insertions(+), 2 deletions(-) rename package/devel/gdb/patches/{ => 7.11}/001-gdb-pr14523-mips-signal-number.patch (100%) rename package/devel/gdb/patches/{ => 7.11}/100-musl_fix.patch (100%) create mode 100644 package/devel/gdb/patches/arc-2016.03/100-no_extern_inline.patch create mode 100644 package/devel/gdb/patches/arc-2016.03/110-no_testsuite.patch create mode 100644 package/devel/gdb/patches/arc-2016.03/120-fix-compile-flag-mismatch.patch create mode 100644 package/devel/gdb/patches/arc-2016.03/200-arc-fix-target-mask.patch diff --git a/package/devel/gdb/Makefile b/package/devel/gdb/Makefile index f6d5fec..2e6b332 100644 --- a/package/devel/gdb/Makefile +++ b/package/devel/gdb/Makefile @@ -8,12 +8,27 @@ include $(TOPDIR)/rules.mk PKG_NAME:=gdb + +ifeq ($(CONFIG_arc),y) +PKG_VERSION:=arc-2016.03-gdb + +PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz +PKG_SOURCE_URL:=https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/archive/$(PKG_VERSION) +PKG_MD5SUM:=775caaf6385c16f20b6f53c0a2b95f79 +GDB_DIR:=binutils-$(PKG_NAME)-$(PKG_VERSION) +else PKG_VERSION:=7.11 -PKG_RELEASE:=1 PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.xz PKG_SOURCE_URL:=@GNU/gdb PKG_MD5SUM:=b5c784685e1cde65ba135feea86b6d75 +GDB_DIR:=$(PKG_NAME)-$(PKG_VERSION) +endif + +PKG_RELEASE:=1 + +PATCH_DIR:=./patches/$(PKG_VERSION) +PKG_BUILD_DIR:=$(BUILD_DIR)/$(GDB_DIR) PKG_BUILD_PARALLEL:=1 PKG_INSTALL:=1 @@ -55,7 +70,11 @@ CONFIGURE_ARGS+= \ --with-system-readline \ --without-expat \ --without-lzma \ - --disable-werror + --disable-werror \ + --disable-binutils \ + --disable-ld \ + --disable-gas \ + --disable-sim CONFIGURE_VARS+= \ ac_cv_search_tgetent="$(TARGET_LDFLAGS) -lncurses -lreadline" diff --git a/package/devel/gdb/patches/001-gdb-pr14523-mips-signal-number.patch b/package/devel/gdb/patches/7.11/001-gdb-pr14523-mips-signal-number.patch similarity index 100% rename from package/devel/gdb/patches/001-gdb-pr14523-mips-signal-number.patch rename to package/devel/gdb/patches/7.11/001-gdb-pr14523-mips-signal-number.patch diff --git a/package/devel/gdb/patches/100-musl_fix.patch b/package/devel/gdb/patches/7.11/100-musl_fix.patch similarity index 100% rename from package/devel/gdb/patches/100-musl_fix.patch rename to package/devel/gdb/patches/7.11/100-musl_fix.patch diff --git a/package/devel/gdb/patches/arc-2016.03/100-no_extern_inline.patch b/package/devel/gdb/patches/arc-2016.03/100-no_extern_inline.patch new file mode 100644 index 0000000..8c18c6e --- /dev/null +++ b/package/devel/gdb/patches/arc-2016.03/100-no_extern_inline.patch @@ -0,0 +1,32 @@ +--- a/sim/common/sim-arange.c ++++ b/sim/common/sim-arange.c +@@ -280,11 +280,7 @@ sim_addr_range_delete (ADDR_RANGE *ar, a + build_search_tree (ar);
