From: Shahab Vahedi Date: Wed, 21 Dec 2022 11:27:05 +0000 (+0100) Subject: Add support for Synopsys ARCv2 processors X-Git-Tag: elfutils-0.189~46 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=de3d46b3e7cb0f8f5bd9164ee83177c13c37355b;p=thirdparty%2Felfutils.git Add support for Synopsys ARCv2 processors There is no regression in tests for an x86_64 build, while the new hello_arc_hs4.ko is added as well. This is the only meaningful test that I could add at the moment, given the features supported by this port. $ cat tests/test-suite.log ========================================== elfutils 0.188: tests/test-suite.log ========================================== # TOTAL: 236 # PASS: 235 # SKIP: 1 # XFAIL: 0 # FAIL: 0 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 SKIP: run-lfs-symbols.sh ======================== LFS testing is irrelevant on this system SKIP run-lfs-symbols.sh (exit status: 77) $ cat tests/run-strip-reloc.sh.log runtest hello_i386.ko runtest hello_x86_64.ko runtest hello_ppc64.ko runtest hello_s390.ko runtest hello_aarch64.ko runtest hello_m68k.ko runtest hello_riscv64.ko runtest hello_csky.ko runtest hello_arc_hs4.ko <-- [ new ARC HS4 test ] runtest /home/shahab/pahole_pkg/elfutils-git/bld_arc/src/strip runtest /home/shahab/pahole_pkg/elfutils-git/bld_arc/src/strip.o runtest strip-uncompressed.o runtest strip-compressed.o runtest testfile-debug-rel-ppc64.o runtest testfile-debug-rel-ppc64-z.o runtest testfile-debug-rel-ppc64-g.o PASS run-strip-reloc.sh (exit status: 0) Signed-off-by: Shahab Vahedi --- diff --git a/backends/ChangeLog b/backends/ChangeLog index 5813ddccc..f28ab89bc 100644 --- a/backends/ChangeLog +++ b/backends/ChangeLog @@ -1,3 +1,12 @@ +2022-12-21 Shahab Vahedi + + * Makefile.am (modules): Add arc. + (arc_SRCS): Added. + (libebl_backends_a_SOURCES): Append arc_SRCS. + * arc_init.c: New file. + * arc_reloc.def: New file. + * arc_symbol.c: New file. + 2022-12-02 Hengqi Chen * Makefile.am (modules): Add loongarch. diff --git a/backends/Makefile.am b/backends/Makefile.am index 0824123dc..f373e5fb0 100644 --- a/backends/Makefile.am +++ b/backends/Makefile.am @@ -37,7 +37,7 @@ AM_CPPFLAGS += -I$(top_srcdir)/libebl -I$(top_srcdir)/libasm \ noinst_LIBRARIES = libebl_backends.a libebl_backends_pic.a modules = i386 sh x86_64 ia64 alpha arm aarch64 sparc ppc ppc64 s390 \ - m68k bpf riscv csky loongarch + m68k bpf riscv csky loongarch arc i386_SRCS = i386_init.c i386_symbol.c i386_corenote.c i386_cfi.c \ i386_retval.c i386_regs.c i386_auxv.c \ @@ -98,12 +98,14 @@ csky_SRCS = csky_attrs.c csky_init.c csky_symbol.c csky_cfi.c \ loongarch_SRCS = loongarch_init.c loongarch_symbol.c +arc_SRCS = arc_init.c arc_symbol.c + libebl_backends_a_SOURCES = $(i386_SRCS) $(sh_SRCS) $(x86_64_SRCS) \ $(ia64_SRCS) $(alpha_SRCS) $(arm_SRCS) \ $(aarch64_SRCS) $(sparc_SRCS) $(ppc_SRCS) \ $(ppc64_SRCS) $(s390_SRCS) \ $(m68k_SRCS) $(bpf_SRCS) $(riscv_SRCS) $(csky_SRCS) \ - $(loongarch_SRCS) + $(loongarch_SRCS) $(arc_SRCS) libebl_backends_pic_a_SOURCES = am_libebl_backends_pic_a_OBJECTS = $(libebl_backends_a_SOURCES:.c=.os) diff --git a/backends/arc_init.c b/backends/arc_init.c new file mode 100644 index 000000000..a7cceceb9 --- /dev/null +++ b/backends/arc_init.c @@ -0,0 +1,59 @@ +/* Initialization of ARC specific backend library. + Copyright (C) 2022 Synopsys Inc. + This file is part of elfutils. + + This file is free software; you can redistribute it and/or modify + it under the terms of either + + * the GNU Lesser General Public License as published by the Free + Software Foundation; either version 3 of the License, or (at + your option) any later version + + or + + * the GNU General Public License as published by the Free + Software Foundation; either version 2 of the License, or (at + your option) any later version + + or both in parallel, as here. + + elfutils is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
