2024-10-04x86: drop largely defunct gas emulationsJan Beulich1-12/+0
Both ELF and COFF have various sub-flavors, each of which would then require its own emulation: Right now when configuring a COFF/PE secondary target (with perhaps an ELF primary one), one gets plain COFF emulation rather than COFF/PE one. As such a multitude of emulations would be unwieldy (and likely fragile) drop gas emulations altogether instead.

2024-01-15gas: x86: synthesize CFI for hand-written asmIndu Bhagat1-6/+13
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.

2023-01-20x86: move insn mnemonics to a separate tableJan Beulich1-1/+1
Using full pointers to reference the insn mnemonic strings is not very efficient. With overall string size presently just slightly over 20k, even a 16-bit value would suffice. Use "unsigned int" for now, as there's no good use we could presently make of the otherwise saved 16 bits. For 64-bit builds this reduces table size by 6.25% (prior to the recent ISA extension additions it would have been 12.5%), with a similar effect on cache occupation of table entries accessed. For PIE builds of gas this also reduces the number of base relocations quite a bit (obviously independent of bitness).

2022-11-15gas: generate .sframe from CFI directivesIndu Bhagat1-4/+10
Currently supported for x86_64 and aarch64 only. [PS: Currently, the compiler has not been adapted to generate ".cfi_sections" with ".sframe" in it. The newly added command line option of --gsframe provides an easy way to try out .sframe support in the toolchain.] gas interprets the CFI directives to generate DWARF-based .eh_frame info. These internal DWARF structures are now consumed by gen-sframe.[ch] sub-system to, in turn, create the SFrame unwind information. These internal DWARF structures are read-only for the purpose of SFrame unwind info generation. SFrame unwind info generation does not impact .eh_frame unwind info generation. Both .eh_frame and .sframe can co-exist in an ELF file, if so desired by the user. Recall that SFrame unwind information only contains the minimal necessary information to generate backtraces and does not provide information to recover all callee-saved registers. The reason being that callee-saved registers other than FP are not needed for stack unwinding, and hence are not included in the .sframe section. Consequently, gen-sframe.[ch] only needs to interpret a subset of DWARF opcodes in gas. More details follow. [Set 1, Interpreted] The following opcodes are interpreted: - DW_CFA_advance_loc - DW_CFA_def_cfa - DW_CFA_def_cfa_register - DW_CFA_def_cfa_offset - DW_CFA_offset - DW_CFA_remember_state - DW_CFA_restore_state - DW_CFA_restore [Set 2, Bypassed] The following opcodes are acknowledged but are not necessary for generating SFrame unwind info: - DW_CFA_undefined - DW_CFA_same_value Anything else apart from the two above-mentioned sets is skipped altogether. This means that any function containing a CFI directive not in Set 1 or Set 2 above, will not have any SFrame unwind information generated for them. Holes in instructions covered by FREs of a single FDE are not representable in the SFrame unwind format. As few examples, following opcodes are not processed for .sframe generation, and are skipped: - .cfi_personality* - .cfi_*lsda - .cfi_escape - .cfi_negate_ra_state - ... Not processing .cfi_escape, .cfi_negate_ra_state will cause SFrame unwind information to be absent for SFrame FDEs that contain these CFI directives, hence affecting the asynchronicity. x86-64 and aarch64 backends need to have a few new definitions and functions for .sframe generation. These provide gas with architecture specific information like the SP/FP/RA register numbers and an SFrame-specific ABI marker. Lastly, the patch also implements an optimization for size, where specific fragments containing SFrame FRE start address and SFrame FDE function are fixed up. This is similar to other similar optimizations in gas, where fragments are sized and fixed up when the associated symbols can be resolved. This optimization is controlled by a #define SFRAME_FRE_TYPE_SELECTION_OPT and should be easy to turn off if needed. The optimization is on by default for both x86_64 and aarch64.

2021-02-24PR23691, gas .y files vs. automatic make dependenciesAlan Modra1-96/+51
A number of targets, bfin, rl78, rx, can show odd failures when bfd/reloc.c changes BFD_RELOC_* enum values, if recompiling over a build dir with existing objects. The problem is caused by bfin-parse.o and similar not being recompiled and so using stale BFD_RELOC_* values. This isn't fixed by making bfin-parse.c depend on bfd/reloc.c, which isn't necessary anyway. bfin-parse.o should have been recompiled due to bfd/bfd.h changing when extracted bfd/reloc.c BFD_RELOC_* values change, but that wasn't happening. The problem is that automake generates a makefile that loads gas/config/.deps/ dependency file for objects with corresponding sources mentioned in EXTRA_as_new_SOURCES. Unless we want to mess around generating explicit dependencies, I think that mean moving some object files to the build gas/config/. This patch does that, removing some hacks for m68k-parse.c that should no longer be necessary, and removes some rules that catered to old bison producing code that triggers compiler warnings.

2021-01-14gas: bfin: build lexer with -WerrorMike Frysinger1-2/+2
The makefile has comments about old versions of bison/yacc generating warnings, but that doesn't apply to the lexer which comes from flex. As far as I can tell, the warnings in the Blackfin lexer can be fixed with defines that have been supported back through flex in 2002. So lets turn on -Werror for it and see if anyone notices. If they do, they can report their exact tool versions so we can record that here.

2020-07-30Unify Solaris procfs and largefile handlingRainer Orth1-1/+2
GDB currently doesn't build on 32-bit Solaris: * On Solaris 11.4/x86: In file included from /usr/include/sys/procfs.h:26, from /vol/src/gnu/gdb/hg/master/dist/gdb/i386-sol2-nat.c:24: /usr/include/sys/old_procfs.h:31:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^~~~~ * On Solaris 11.3/x86 there are several more instances of this. The interaction between procfs and large-file support historically has been a royal mess on Solaris: * There are two versions of the procfs interface: ** The old ioctl-based /proc, deprecated and not used any longer in either gdb or binutils. ** The `new' (introduced in Solaris 2.6, 1997) structured /proc. * There are two headers one can possibly include: ** <procfs.h> which only provides the structured /proc, definining _STRUCTURED_PROC=1 and then including ... ** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based /proc, but provides structured /proc if _STRUCTURED_PROC == 1. * procfs and the large-file environment didn't go well together: ** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit compilations when the large-file environment was active (_FILE_OFFSET_BITS == 64). ** In both Solaris 11.4 and Illumos, this restriction was lifted for structured /proc. So one has to be careful always to define _STRUCTURED_PROC=1 when testing for or using <sys/procfs.h> on Solaris. As the errors above show, this isn't always the case in binutils-gdb right now. Also one may need to disable large-file support for 32-bit compilations on Solaris. config/largefile.m4 meant to do this by wrapping the AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because it neglects the _STRUCTURED_PROC part. To make things even worse, since GCC 9 g++ predefines _FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to enable large-file support, this has no effect, breaking the gdb build. This patch addresses all this as follows: * All tests for the <sys/procfs.h> header are made with _STRUCTURED_PROC=1, the definition going into the various config.h files instead of having to make them (and sometimes failing) in the affected sources. * To cope with the g++ predefine of _FILE_OFFSET_BITS=64, -U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had been far easier to have just #undef _FILE_OFFSET_BITS in config.h, but unfortunately such a construct in config.in is commented by config.status irrespective of indentation and whitespace if large-file support is disabled. I found no way around this and putting the #undef in several global headers for bfd, binutils, ld, and gdb seemed way more invasive. * Last, the applicability check in largefile.m4 was modified only to disable largefile support if really needed. To do so, it checks if <sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it doesn't, the disabling only happens if gdb exists in-tree and isn't disabled, otherwise (building binutils from a tarball), there's no conflict. What initially confused me was the check for $plugins here, which originally caused the disabling not to take place. Since AC_PLUGINGS does enable plugin support if <dlfcn.h> exists (which it does on Solaris), the disabling never happened. I could find no explanation why the linker plugin needs large-file support but thought it would be enough if gld and GCC's lto-plugin agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not enough: lto-plugin uses the simple-object interface from libiberty, which includes off_t arguments. So to fully disable large-file support would mean also disabling it in libiberty and its users: gcc and libstdc++-v3. This seems highly undesirable, so I decided to disable the linker plugin instead if large-file support won't work. The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to predefined _FILE_OFFSET_BITS=64). Also regtested on amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4), x86_64-pc-linux-gnu and i686-pc-linux-gnu. config: * largefile.m4 (ACX_LARGEFILE) <sparc-*-solaris*|i?86-*-solaris*>: Check for <sys/procfs.h> incompatilibity with large-file support on Solaris.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+9
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.
