2018-08-31ld: Append -mx86-used-note=no to ASFLAGSH.J. Lu5-0/+41
Since x86 assembler may generate .note.gnu.property section, append -mx86-used-note=no to tests which don't expect .note.gnu.property section on ELF/x86 targets. * testsuite/ld-elf/elf.exp (ASFLAGS): Save, append -mx86-used-note=no and restore. * testsuite/ld-ifunc/ifunc.exp (ASFLAGS): Likewise. * testsuite/ld-scripts/defined.exp (ASFLAGS): Likewise. * testsuite/ld-scripts/overlay-size.exp (ASFLAGS): Likewise
2018-08-31ld: Append -Wa,-mx86-used-note=no for S-records testsH.J. Lu2-0/+12
Since x86 assembler may generate .note.gnu.property section and S-records can't handle .note.gnu.property sections, add -mx86-used-note=no to S-records tests on ELF/x86 targets to avoid .note.gnu.property section. * testsuite/ld-srec/srec.exp: Append -Wa,-mx86-used-note=no to CC and CXX on ELF/x86 targets.

2018-08-27x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bitH.J. Lu8-0/+130
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only relocatable objects which don't contain any instructions, linker shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs. This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has the GNU_PROPERTY_X86_UINT32_VALID bit. bfd/ * elfxx-x86.c (_bfd_x86_elf_parse_gnu_properties): Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit. binutils/ * readelf.c (decode_x86_isa): Print <None> if bitmask only contains the GNU_PROPERTY_X86_UINT32_VALID bit.

2018-08-26Delay evaluation of alignment expressions in output sectionsAlan Modra10-40/+88
git commit 702d16713 broke expressions using CONSTANT(COMMONPAGESIZE) in ALIGN or SUBALIGN of output section statements, because these optional fields were evaluated at script parse time and the patch in question delayed setting of config.commonpagesize.

2018-08-24x86: Update GNU_PROPERTY_X86_XXX macrosH.J. Lu55-48/+361
This patch updates GNU_PROPERTY_X86_XXX macros: 1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.

GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.

GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs and the property is present in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff 4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED and GNU_PROPERTY_X86_FEATURE_2_XXX bits. GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful. A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.

2018-08-24ehdr_start twiddlesAlan Modra2-12/+21
We force __ehdr_start to defined in before_allocation, then restore the type and a union after dynamic symbols have been allocated. The union contains a number of structs, all starting with a "next" pointer, and various fields depending on the symbol type. The old code restored the entire union, but it isn't necessary to restore the "next" pointer, and in fact it could be wrong if __ehdr_start happened to be last on the list and some symbols were added before restoring. * emultempl/elf32.em (before_allocation): Don't restore __ehdr_start u.*.next pointer.

2018-08-07PowerPC64 EH info for _notoc linkage stubsAlan Modra5-9/+53
This patch generates EH info for the new _notoc linkage stubs, to support unwinding from asynchronous signal handlers. Unwinding through the __tls_get_addr_opt stub was already supported, but that was just a single stub. With multiple stubs the EH opcodes need to be emitted and sized when iterating over stubs, so this is done when emitting and sizing the stub code. Emitting the CIEs and FDEs is done when sizing the stubs, as we did before in order to have the linker generated FDEs indexed in .eh_frame_hdr. I moved the final tweaks to FDEs from ppc64_elf_finish_dynamic_sections to ppc64_elf_build_stubs simply because it's tidier to be done with them at that point. bfd/ * elf64-ppc.c (struct map_stub): Delete tls_get_addr_opt_bctrl.

R_PPC64_REL24_NOTOC is used on calls like "bl foo@notoc" to tell the linker that linkage stubs for PLT calls or long branches can't use r2 for pic addressing. Instead, new stubs that generate pc-relative addresses are used. One complication is that pc-relative offsets to the PLT may need to be 64-bit in large programs, in contrast to the toc-relative addressing used by older PLT linkage stubs where a 32-bit offset is sufficient until the PLT itself exceeds 2G in size. .eh_frame info to cover the _notoc stubs is yet to be implemented. bfd/ * elf64-ppc.c (ADDI_R12_R11, ADDI_R12_R12, LIS_R12), (ADDIS_R12_R11, ORIS_R12_R12_0, ORI_R12_R12_0), (SLDI_R12_R12_32, LDX_R12_R11_R12, ADD_R12_R11_R12): Define.

2018-08-05Lose _r2off in powerpc64 stub namesAlan Modra3-6/+11
Not a lot is conveyed by putting _r2off in a stub symbol that can't be seen by inspecting the stub code or the toc restoring instruction immediately after a call via such a stub.

2018-08-01Re: PowerPC64 __tls_get_addr_opt stub .eh_frame fixAlan Modra2-1/+6
The modified test failed on some powerpc targets due to differences in default hash style. If the default hash style is both, then more sections are created, bumping section ids. Section id is used in stub symbols and although the test is careful to not depend on id in labels, the stub hash traversal order changes when stub names change. That lead to the stubs being emitted in a different order and thus not matching expected output. * testsuite/ld-powerpc/powerpc.exp: Run tlsopt5 with hash-style specified.
2018-08-01PowerPC64 __tls_get_addr_opt stub .eh_frame fixAlan Modra5-6/+29
This patch sets stub_offset in ppc_size_one_stub rather than in ppc_build_one_stub. That allows the plt stub alignment to be done in just ppc_size_one_stub rather than both functions.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner44-4/+1132
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.

2018-07-25Enhance powerpc ld -r --relaxAlan Modra5-18/+47
One of the ill effects of ld -r is to mash together sections. That can result in reduced icache performance at runtime due to unexpected movement of code.
