2018-03-02[ARM] Fix NULL dereference of march_ext_optThomas Preud'homme2-1/+6
Commit 4d354d8b8932d450c77fd52f3501662827523014 introduced a NULL pointer dereference by replacing a pointer assignment by a pointer dereference assignment without adding a NULL pointer check. This patch fixes it. 2018-03-02 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (md_begin): Add NULL pointer check before dereferencing march_ext_opt.
2018-03-01[ARM] Clean up selection of feature bitsThomas Preud'homme2-111/+171
I've always found the code in ARM backend of gas to control what CPU/architecture and FPU are selected by the user and to support autodetection of features complex and confusing. Chief among the issues I have with that code is the lack of comments to explain the meaning of the various variables. This patch addresses that and much more: - add comments to explain meaning of all arm_feature_set variables - keep track of currently selected CPU, extensions and FPU in a separate set of new variables - make naming of variable more consistent - remove dead code - simplify handling of extensions The overall approach is as follows: * restrict m*_opt variable to hold the feature bits of the corresponding mcpu/march/mfpu command-line options * record selected CPU, extensions and FPU in new selected_* during md_begin * whenever a .cpu/.arch/.arch_extension/.fpu directive is met, update the corresponding selected_* variables (eg. selected_arch, then selected_cpu for a .cpu or .arch directive) and then finally cpu_variant from them * pass extension feature set pointer by value to arm_parse_extension since it's only ever called from arm_parse_cpu and arm_parse_arch which allocate the extension feature set themselves * likewise, remove allocation from s_arm_arch_extension since the use of arm_feature_set structure for selected_ext rather than a pointer alleviate the need for it * in autodetection mode, only set all CPU fits in cpu_variant but leave selected_cpu* variables unset * in md_begin, remove dead "else if" to set a default FPU when no FPU was selected. Setting a default FPU based on CPU as did the code before it turn dead should be based on the default FPU field of the CPU and architecture table as will be done in a separate patch. Logic is wrong anyway since it sets VFP2 as default FPU for Armv6-M and Armv7-M Hopefully that should be enough to understand the change but if not feel free to ask questions about the patch. While I believe the new code is easier to understand, it remains complex and the old one was even more complex so the change is difficult to understand. 2018-03-01 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (cpu_variant, arm_arch_used, thumb_arch_used, legacy_cpu, legacy_fpu, mcpu_cpu_opt, dyn_mcpu_ext_opt, mcpu_fpu_opt, march_cpu_opt, dyn_march_ext_opt, march_fpu_opt, mfpu_opt, object_arch, selected_cpu): Comment meaning of variables.

2018-02-27x86: Add -O[2|s] assembler command-line optionsH.J. Lu21-2/+773
On x86, some instructions have alternate shorter encodings: 1. When the upper 32 bits of destination registers of andq $imm31, %r64 testq $imm31, %r64 xorq %r64, %r64 subq %r64, %r64 known to be zero, we can encode them without the REX_W bit: andl $imm31, %r32 testl $imm31, %r32 xorl %r32, %r32 subl %r32, %r32 This optimization is enabled with -O, -O2 and -Os. 2. Since 0xb0 mov with 32-bit destination registers zero-extends 32-bit immediate to 64-bit destination register, we can use it to encode 64-bit mov with 32-bit immediates. This optimization is enabled with -O, -O2 and -Os. 3. Since the upper bits of destination registers of VEX128 and EVEX128 instructions are extended to zero, if all bits of destination registers of AVX256 or AVX512 instructions are zero, we can use VEX128 or EVEX128 encoding to encode AVX256 or AVX512 instructions. When 2 source registers are identical, AVX256 and AVX512 andn and xor instructions: VOP %reg, %reg, %dest_reg can be encoded with VOP128 %reg, %reg, %dest_reg This optimization is enabled with -O2 and -Os. 4. 16-bit, 32-bit and 64-bit register tests with immediate may be encoded as 8-bit register test with immediate. This optimization is enabled with -Os. This patch does: 1. Add {nooptimize} pseudo prefix to disable instruction size optimization. 2. Add optimize to i386_opcode_modifier to tell assembler that encoding of an instruction may be optimized. gas/ PR gas/22871 * NEWS: Mention -O[2|s]. * config/tc-i386.c (_i386_insn): Add no_optimize.

Documentation for .arch_extension says it accepts the same architectural extensions as those accepted by -mcpu.

2018-02-17Add .nop assembler directiveH.J. Lu30-111/+812
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits SIZE bytes filled with no-op instructions. SIZE is absolute expression. The optional CONTROL byte controls how no-op instructions should be generated. If the comma and @var{control} are omitted, CONTROL is assumed to be zero. For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size limit of a single no-op instruction. The valid values of CONTROL byte are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode, between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit is set to the maximum supported size. 2 new relax states, rs_space_nop and rs_fill_nop, are added to enum _relax_state, which are similar to rs_space and rs_fill, respectively, but they fill with no-op instructions, instead of a single byte. A target backend must override the default md_generate_nops to generate proper no-op instructions.

2018-02-13x86-64: Generate branch with PLT32 relocationH.J. Lu10-23/+85
Since there is no need to prepare for PLT branch on x86-64, generate R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be used as a marker for 32-bit PC-relative branches. To compile Linux kernel, this patch: From: "H.J. Lu" <hjl.tools@gmail.com> Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32 On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared objects must use PIC PLT. To use PIC PLT, you need to load _GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on x86-64 since x86-64 uses PC-relative PLT. On x86-64, for 32-bit PC-relative branches, we can generate PLT32 relocation, instead of PC32 relocation, which can also be used as a marker for 32-bit PC-relative branches. Linker can always reduce PLT32 relocation to PC32 if function is defined locally. Local functions should use PC32 relocation. As far as Linux kernel is concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32 since Linux kernel doesn't use PLT. is needed.

Use `mips-*-sysv4*' rather than `mips-*-sysv4*MP*' to match the system type for System V Release 4 MIPS targets, removing a GAS target selection failure: Assembler messages: Fatal error: selected target format 'elf32-bigmips' unknown on any assembly attempt with `mips-sysv4' and equivalent target configurations. These would typically be called `mips-sni-sysv4' (Sinix) vs `mips-dde-sysv4.2MP' (Supermax). This corrects commit 8614eeee67f9 ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, making GAS target selection match commit dd745cfae548 ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, and commit 3548145dcbf6 ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, which added support for these targets to BFD and LD respectively. gas/ * configure.tgt: Use `mips-*-sysv4*' rather than `mips-*-sysv4*MP*'.
