* coff-go32-exe: support variable-length stubsJan W. Jagersma2020-04-023-48/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stub size in GO32 executables has historically been fixed at 2048 bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if any further expansion is desired, this must first be patched in bfd. This series includes three patches: The first changes the meaning of the bfd->origin field slightly, so that target code can use this to specify an offset into the file where the actual bfd is located. The second patch then uses this to enable support for variable-sized stubs in the coff-go32-exe format. The final patch is only a cleanup, it normalizes function and variable names in coff-stgo32.c so that they all begin with the same prefix. bfd * bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add bfd->origin to file offset. * bfdwin.c (bfd_get_file_window): Likewise. * bfd.c: Clarify the use of the bfd->origin field. * bfd-in2.h: Regenerate. * coff-i386.c: Don't include go32exe.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the riscv privilege spec, some CSR are only valid when rv32 or the specific extension is set. We extend the DECLARE_CSR and DECLARE_CSR_ALIAS to record more informaton we need, and then check whether the CSR is valid according to these information. We report warning message when the CSR is invalid, so we have a choice between error and warning by --fatal-warnings option. Also, a --no-warn/-W option is used to turn the warnings off, if people don't want the warnings. gas/ * config/tc-riscv.c (enum riscv_csr_class): New enum.

* [binutils][arm] arm support for ARMv8.m Custom Datapath ExtensionMatthew Malcomson2020-02-102-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of a series that adds support for the Armv8.m ARMv8.m Custom Datapath Extension to binutils. This patch introduces the Custom Instructions Class 1/2/3 (Single/ Dual, Accumulator/Non-accumulator varianats) to the arm backend. The following Custom Instructions are added: cx1, cx1a, cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da. Specification can be found at https://developer.arm.com/docs/ddi0607/latest This patch distinguishes between enabling CDE for different coprocessor numbers by defining multiple architecture flags. This means that the parsing of the architecture extension flags is kept entirely in the existing code path. We introduce a new IT block state to indicate the behaviour of these instructions. This new state allows being used in an IT block or outside an IT block, but does not allow the instruction to be used inside a VPT block. We need this since the CX*A instruction versions can be used in IT blocks, but they aren't to have the conditional suffixes on them. Hence we need to mark an instruction as allowed in either position. We also need a new flag to objdump, in order to determine whether to disassemble an instruction as CDE related or not.

* [binutils][arm] PR25376 Change MVE into a CORE_HIGH featureAndre Vieira2020-01-162-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves MVE feature bits into the CORE_HIGH section. This makes sure .fpu and -mfpu does not reset the bits set by MVE. This is important because .fpu has no option to "set" these same bits and thus, mimic'ing GCC, we choose to define MVE as an architecture extension rather than put it together with other the legacy fpu features. This will enable the following behavior: .arch armv8.1-m.main .arch mve .fpu fpv5-sp-d16 #does not disable mve. vadd.i32 q0, q1, q2 This patch also makes sure MVE is not taken into account during auto-detect. This was already the case, but because we moved the MVE bits to the architecture feature space we must make sure ARM_ANY does not include MVE. gas/ChangeLog: 2020-01-16 Andre Vieira <andre.simoesdiasvieira@arm.com> PR 25376 * config/tc-arm.c (mve_ext, mve_fp_ext): Use CORE_HIGH.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempting to build GDB in Ubuntu 16.04.6 LTS on x86_64, I ran into warnings that caused the build to fail: binutils-gdb/gdb/gdbsupport/safe-strerror.c:44:1: error: ‘char* select_strerror_r(char*, char*)’ defined but not used [-Werror=unused-function] select_strerror_r (char *res, char *) The diagnostic macro DIAGNOSTIC_IGNORE_UNUSED_FUNCTION seems to expand correctly to its respective pragma, but this doesn't seem to have an effect on the warning. I tried to use the pragma explicitly and got the same result. ATTRIBUTE_UNUSED works fine in this case if you put it in both functions, which should fix warnings for both gdb and gdbserver builds. The compiler version is gcc (Ubuntu 5.4.0-6ubuntu1~16.04.11) 5.4.0 20160609. This is likely the result of PR64079 in GCC, which was fixed by commit 9e96f1e1b9731c4e1ef4fbbbf0997319973f0537.

* Arm: Change CRC from fpu feature to archititectural extensionMihail Ionescu2019-11-222-16/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the CRC extension to use the core feature bits instead of the coproc/fpu feature bits. CRC is not an fpu feature and it causes issues with the new fpu reset patch (f439988037a589de3798f44e7268301adaec21a9). CRC can be set using the '.arch_extension' directive, which sets bits in the coproc bitfield. When a '.fpu' directive is encountered, the CRC feature bit gets removed and there is no way to set it back using '.fpu'. With this patch, CRC will be marked in the feature core bits, which prevents it from getting removed when setting/changing the fpu options. gas/ChangeLog: * config/tc-arm.c (arm_ext_crc): New.

* gas: Add --gdwarf-cie-version command line flagAndrew Burgess2019-11-182-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
