2024-01-15gas: x86: synthesize CFI for hand-written asmIndu Bhagat1-0/+5
This patch adds support in GAS to create generic GAS instructions (a.k.a., the ginsn) for the x86 backend (AMD64 ABI only at this time). Using this ginsn infrastructure, GAS can then synthesize CFI for hand-written asm for x86_64. A ginsn is a target-independent representation of the machine instructions. One machine instruction may need one or more ginsn. This patch also adds skeleton support for printing ginsn in the listing output for debugging purposes. Since the current use-case of ginsn is to synthesize CFI, the x86 target needs to generate ginsns necessary for the following machine instructions only: - All change of flow instructions, including all conditional and unconditional branches, call and return from functions. - All register saves and unsaves to the stack. - All instructions affecting the two registers that could potentially be used as the base register for CFA tracking. For SCFI, the base register for CFA tracking is limited to REG_SP and REG_FP only for now. The representation of ginsn is kept simple: - GAS instruction has GINSN_NUM_SRC_OPNDS (defined to be 2 at this time) number of source operands and one destination operand at this time. - GAS instruction uses DWARF register numbers in its representation and does not track register size. - GAS instructions carry location information (file name and line number). - GAS instructions are ID's with a natural number in order of their addtion to the list. This can be used as a proxy for the static program order of the corresponding machine instructions. Note that, GAS instruction (ginsn) format does not support GINSN_TYPE_PUSH and GINSN_TYPE_POP. Some architectures, like aarch64, do not have push and pop instructions, but rather STP/LDP/STR/LDR etc. instructions. Further these instructions have a variety of addressing modes, like offset, pre-indexing and post-indexing etc. Among other things, one of differences in these addressing modes is _when_ the addr register is updated with the result of the address calculation: before or after the memory operation. To best support such needs, the generic instructions like GINSN_TYPE_LOAD, GINSN_TYPE_STORE together with GINSN_TYPE_ADD, and GINSN_TYPE_SUB may be used. The functionality provided in ginsn.c and scfi.c is compiled in when a target defines TARGET_USE_SCFI and TARGET_USE_GINSN. This can be revisited later when there are other use-cases of creating ginsn's in GAS, apart from the current use-case of synthesizing CFI for hand-written asm. Support is added only for System V AMD64 ABI for ELF at this time. If the user enables SCFI with --32, GAS issues an error: "Fatal error: SCFI is not supported for this ABI" For synthesizing (DWARF) CFI, the SCFI machinery requires the programmer to adhere to some pre-requisites for their asm: - Hand-written asm block must begin with a .type foo, @function It is highly recommended to, additionally, also ensure that: - Hand-written asm block ends with a .size foo, .-foo The SCFI machinery encodes some rules which align with the standard calling convention specified by the ABI. Apart from the rules, the SCFI machinery employs some heuristics. For example: - The base register for CFA tracking may be either REG_SP or REG_FP. - If the base register for CFA tracking is REG_SP, the precise amount of stack usage (and hence, the value of REG_SP) must be known at all times. - If using dynamic stack allocation, the function must switch to FP-based CFA. This means using instructions like the following (in AMD64) in prologue: pushq %rbp movq %rsp, %rbp and analogous instructions in epilogue. - Save and Restore of callee-saved registers must be symmetrical. However, the SCFI machinery at this time only warns if any such asymmetry is seen. These heuristics/rules are architecture-independent and are meant to employed for all architectures/ABIs using SCFI in the future. gas/ * Makefile.am: Add new files. * Makefile.in: Regenerated. * as.c (defined): Handle documentation and listing option for ginsns and SCFI. * config/obj-elf.c (obj_elf_size): Invoke ginsn_data_end.

2024-01-15gas: add new command line option --scfi=experimentalIndu Bhagat1-2/+21
When the command line option --scfi=experimenta is passed to the GNU assembler, it will synthesize DWARF call frame information (CFI) for the input assembly. The option --scfi=experimental will also ignore most of the existing .cfi_* directives, if already contained in the provided input file. Only the following CFI directives will not be ignored: - .cfi_sections, - .cfi_label, - .cfi_signal_frame To use SCFI, a target will need to: - define TARGET_USE_SCFI and TARGET_USE_GINSN, and other necessary definitions, - provide means to help GAS understand the target specific instruction semantics by creating ginsns. The upcoming support for SCFI is inteded to be experimental, hence the option --scfi=experimental. The --scfi= may see more options like --scfi=[all,none] added in future, once the SCFI support in GAS is mature and robust. The offering may also see for example, an --scfi=inline option for dealing with inline asm may be added in the future. In --scfi=inline option, the GNU assembler may consume (and not ignore) the compiler generated CFI for the code surrounding the inline asm. Also document the option. gas/ * as.c (show_usage): Add support for --scfi=experimental. (parse_args): Likewise. * as.h (enum synth_cfi_type): Define new type. * doc/as.texi: Document the new option.

2023-03-17gas: expose flag_macro_alternate globallyJan Beulich1-3/+1

2023-03-17gas: isolate macro_strip_at to macro.cJan Beulich1-5/+1
This removes a leftover from i960 support; with that nothing is left which would set macro_strip_at to non-zero, so the variable is converted to a #define (retaining the logic in case a new user would appear) and macro_init()'s respective parameter is dropped.

2023-03-03gas: default .debug section compression method adjustmentsJan Beulich1-2/+7
While commit b0c295e1b8d0 ("add --enable-default-compressed-debug- sections-algorithm configure option") adjusted flag_compress_debug's initializer, it didn't alter the default used when the command line option was specified with an (optional!) argument. This rendered help text inconsistent with actual behavior in certain configurations. As to help text - the default reported there clearly shouldn't be affected by a possible earlier --compress-debug-sections= option, so flag_compress_debug can't be used when emitting usage information.

2022-07-09gas: rename md_end to md_finishAlan Modra1-2/+2
Currently md_end is typically used for some final actions rather than freeing memory like other *_end functions. Rename it to md_finish, and rename target implementation. The renaming of target functions makes it possible to find them all with "grep md_finish", eg. md_mips_end is renamed to mips_md_finish, not md_mips_finish. This patch leaves a number of md_end functions unchanged, those that either do nothing or deallocate memory, and calls them late. The idea here is that target maintainers implement md_end functions to tidy memory, if anyone cares. Freeing persistent memory in gas is not at all important, except that it can hide more important memory leaks, those that happen once per some frequent gas operation, amongst these unimportant memory leaks. * as.c (main): Rename md_end to md_finish. * config/tc-alpha.c, * config/tc-alpha.h, * config/tc-arc.c, * config/tc-arc.h, * config/tc-arm.c, * config/tc-arm.h, * config/tc-csky.c, * config/tc-csky.h, * config/tc-ia64.c, * config/tc-ia64.h, * config/tc-mcore.c, * config/tc-mcore.h, * config/tc-mips.c, * config/tc-mips.h, * config/tc-mmix.c, * config/tc-mmix.h, * config/tc-msp430.c, * config/tc-msp430.h, * config/tc-nds32.c, * config/tc-nds32.h, * config/tc-ppc.c, * config/tc-ppc.h, * config/tc-pru.c, * config/tc-pru.h, * config/tc-riscv.c, * config/tc-riscv.h, * config/tc-s390.c, * config/tc-s390.h, * config/tc-sparc.c, * config/tc-sparc.h, * config/tc-tic4x.c, * config/tc-tic4x.h, * config/tc-tic6x.c, * config/tc-tic6x.h, * config/tc-v850.c, * config/tc-v850.h, * config/tc-xtensa.c, * config/tc-xtensa.h, * config/tc-z80.c, * config/tc-z80.h: Similarly. * output-file.c (output_file_close): Call md_end.

2020-08-28gas: Handle bad -gdwarf options, just like bad --gdwarf options.Mark Wielaard1-0/+7
parse_args uses getopt_long_only so it can handle long options both with double and single dash. But this means that some single dash options like -gdwarf-1 don't generate an error (unlike --gdwarf-1). This is especially confusing since there is also --gdwarf2, but no --gdwarf4 (it is --gdwarf-4). When giving -gdwarf4 the option is silently interpreted as -g (which set dwarf_version to 2). This causes some confusion for people who don't expect this and suddenly get DWARF2 instead of DWARF4 as they might expect. So make it so that the -gdwarf<unknown> creates an error, just like --gdwarf<unknown> would.

2019-11-28gas/riscv: Produce version 3 DWARF CIE by defaultAndrew Burgess1-4/+6
The flag controlling the default DWARF CIE version to produce now starts with the value -1. This can be modified with the command line flag as before, but after command line flag processing, in md_after_parse_args targets can, if the global still has the value -1, override this value. This gives a target specific default. If a CIE version is not select either by command line flag, or a target specific default, then some new code in dwarf2_init now select a global default. This remains as version 1 to match previous behaviour. This RISC-V has a target specific default of version provided, this make the return column uleb128, which means we can use all DWARF registers include CSRs. I chose to switch to version 3 rather than version 4 as this is most similar to the global default (version 1). Switching to version 4 adds additional columns to the CIE header. gas/ChangeLog: * as.c (flag_dwarf_cie_version): Change initial value to -1, and update comment. * config/tc-riscv.c (riscv_after_parse_args): Set flag_dwarf_cie_version if it has not already been set. * dwarf2dbg.c (dwarf2_init): Initialise flag_dwarf_cie_version if needed. * testsuite/gas/riscv/default-cie-version.d: New file. * testsuite/gas/riscv/default-cie-version.s: New file. ld/ChangeLog: * testsuite/ld-elf/eh5.d: Accept version 3 DWARF CIE.

2019-11-18gas: Add --gdwarf-cie-version command line flagAndrew Burgess1-0/+17
Add a flag to control the version of CIE that is generated. By default gas produces CIE version 1, and this continues to be the default after this patch. However, a user can now provide --gdwarf-cie-version=NUMBER to switch to either version 3 or version 4 of CIE, version 2 was never released, and so causes an error as does any number less than 1 or greater than 4. Producing version 4 CIE requires two new fields to be added to the CIE, an address size field, and an segment selector field. For a flat address space the DWARF specification indicates that the segment selector should be 0, and the address size fields just contains the address size in bytes. For now we support 4 or 8 byte addresses, and the segment selector is always produced as 0. At some future time we might need to allow targets to override this. gas/ChangeLog: * as.c (parse_args): Parse --gdwarf-cie-version option.

2019-09-19bfd_section_* macrosAlan Modra1-4/+4
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

This patch performs a run-time test that a shared libbfd.so has been compiled with the same size bfd_vma as that of apps using the library. On a 32-bit host it is easily possible to have one libbfd.so compiled to support 64-bit targets (or configured with --enable-64-bit-bfd) while another only supports 32-bit targets. The two libraries will have differently sized bfd_vma types, and if the wrong one is loaded all sorts of weird behaviour might be seen. bfd/ PR 23534 * init.c (BFD_INIT_MAGIC): Define.
