2018-08-01[PATCH, LD, AArch64] Fix ifunc testismsAndre Simoes Dias Vieira2-2/+3
This patch fixes some ifunc testisms after H.J. Lu's patch to enable the use of IFUNC pointers in position dependent code for binutils. See PR LD/23169 in binutils bugzilla. The aarch64 ifunc error message test was changed to no longer expect this error message as this is now an accepted combination. This patch also disables the executable tests added by H.J. Lu for aarch64, just as Alan Modra did with his patch, as these tests only seem to work on some architectures. ld/ChangeLog: 2018-07-19 Andre Vieira <andre.simoesdiasvieira@arm.com> * testsuite/ld-aarch64/ifunc-9.d: Remove no longer expected error. * testsuite/ld-ifunc/ifunc.exp: Disable tests for aarch64.

PR gas/23465 In commit b5014f7af2 I've removed (instead of replaced) a conditional, resulting in addressing forms not allowing 8-bit displacements to now get their displacements scaled under certain circumstances. Re-add the missing conditional.

2018-07-23x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if neededH.J. Lu20-25/+248
When -z separate-code, which is enabled by default for Linux/x86, is used to create executable, ld won't place any data in the code-only PT_LOAD segment. If there are no data sections placed before the code-only PT_LOAD segment, the program headers won't be mapped into any PT_LOAD segment. When the executable tries to access it (based on the program header address passed in AT_PHDR), it will lead to segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if there may be no data sections before the text section so that the first PT_LOAD segment won't be code-only and will contain the program header. Testcases are adjusted to either pass "-z noseparate-code" to ld or discard the .note.gnu.property section. A Linux/x86 run-time test is added. bfd/ PR ld/23428 * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the separate code program header is needed, make sure that the first read-only PT_LOAD segment has no code by adding a GNU_PROPERTY_X86_ISA_1_USED note. ld/ PR ld/23428 * testsuite/ld-elf/linux-x86.S: New file. * testsuite/ld-elf/linux-x86.exp: Likewise. * testsuite/ld-elf/pr23428.c: Likewise. * testsuite/ld-elf/sec64k.exp: Pass "-z noseparate-code" to ld for Linux/x86 targets. * testsuite/ld-i386/abs-iamcu.d: Likewise. * testsuite/ld-i386/abs.d: Likewise. * testsuite/ld-i386/pr12718.d: Likewise. * testsuite/ld-i386/pr12921.d: Likewise. * testsuite/ld-x86-64/abs-k1om.d: Likewise. * testsuite/ld-x86-64/abs-l1om.d: Likewise. * testsuite/ld-x86-64/abs.d: Likewise. * testsuite/ld-x86-64/pr12718.d: Likewise. * testsuite/ld-x86-64/pr12921.d: Likewise. * testsuite/ld-linkonce/zeroeh.ld: Discard .note.gnu.property section. * testsuite/ld-scripts/print-memory-usage.t: Likewise. * testsuite/ld-scripts/size-2.t: Likewise. * testsuite/lib/ld-lib.exp (run_ld_link_exec_tests): Use ld to create executable if language is "asm".

2018-07-18x86: Split vcvtps2{,u}qq and vcvttps2{,u}qqH.J. Lu7-21/+125
After commit 1b54b8d7e4fc8055f9220a5287e8a94d8a65a88d Author: Jan Beulich <jbeulich@novell.com> Date: Mon Dec 18 09:36:14 2017 +0100 x86: fold RegXMM/RegYMM/RegZMM into RegSIMD ... qualified by their respective sizes, allowing to drop FirstXmm0 at the same time. folded RegXMM, RegYMM and RegZMM into RegSIMD, it's no longer impossible to distinguish if Xmmword can represent a memory reference when operand specification contains SIMD register. For example, template operands specification like these RegXMM|...|Xmmword|... and RegXMM|... The Xmmword bitfield is always set by RegXMM which is represented by "RegSIMD|Xmmword". This patch splits each of vcvtps2qq, vcvtps2uqq, vcvttps2qq and vcvttps2uqq into 2 templates: one template only has RegXMM source operand and the other only has mempry source operand. gas/ PR gas/23418 * testsuite/gas/i386/xmmword.s: Add tests for vcvtps2qq, vcvtps2uqq, vcvttps2qq and vcvttps2uqq. * testsuite/gas/i386/xmmword.l: Updated. opcodes/ PR gas/23418 * i386-opc.h (Byte): Update comments.

2018-07-13Hide dynamic symbols in discarded sectionsAlan Modra2-2/+12
This is a followup to git commit 97196564c7 "Strip global symbol defined in discarded section". If a symbol defined in a discarded section was dynamic, that patch left .dynsym with holes (ie. all zero entries). For example, the following from libstdc++.so: Symbol table '.dynsym' contains 6090 entries: Num: Value Size Type Bind Vis Ndx Name 0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000000a74e0 0 SECTION LOCAL DEFAULT 10 2: 0000000000264180 0 SECTION LOCAL DEFAULT 17 3: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_addUserCommitAction 4: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_memcpyRtWn 5: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 5 found at index >= .dynsym's sh_info value of 3 6: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 6 found at index >= .dynsym's sh_info value of 3 [snip] This patch removes the symbols from .dynsym too.
