2019-07-10	Don't include gdbarch.h from defs.h	Tom Tromey	1	-0/+1
	I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some -nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.
2019-02-08	RISC-V: Add FP register core file support.	Jim Wilson	1	-2/+21
	This adds fp reg support similar to the existing general reg support. This fixes one gdb testsuite failure FAIL: gdb.base/gcore.exp: corefile restored system registers which fails without the patch because fcsr was missing. Otherwise, no regressions with riscv64-linux native testsuite run. gdb/ * riscv-linux-tdep.c (riscv_linux_fregmap): New. (riscv_linux_fregset): New. (riscv_linux_iterate_over_regset_sections): Call cb for .reg2 section.
2019-01-01	Update copyright year range in all GDB files.	Joel Brobecker	1	-1/+1
	This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-10-26	RISC-V: Linux signal frame support.	Jim Wilson	1	-0/+80
	Add support for recognizing signal trampolines, parsing the signal frame, and reading register values from it. gdb/ * riscv-linux-tdep.c: Include tramp-frame.h and trad-frame.h. (riscv_linux_sigframe_init): Declare. (RISCV_INST_LI_A7_SIGRETURN, RISCV_INT_ECALL): New. (riscv_linux_sigframe): New. (SIGFRAME_SIGINFO_SIZE, UCONTEXT_MCONTEXT_OFFSET): New. (riscv_linux_sigframe_init): Define. (riscv_linux_init_abi): Call tramp_frame_prepend_unwinder.
2018-08-13	Split size in regset section iterators	Alan Hayward	1	-1/+1
	In the existing code, when using the regset section iteration functions, the size parameter is used in different ways. With collect, size is used to create the buffer in which to write the regset. (see linux-tdep.c::linux_collect_regset_section_cb). With supply, size is used to confirm the existing regset is the correct size. If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size. Effectively, size is the minimum possible size of the regset. (see corelow.c::get_core_register_section). There are currently no targets with both REGSET_VARIABLE_SIZE and a collect function. In SVE, a corefile can contain one of two formats after the header, both of which are different sizes. However, when writing a core file, we always want to write out the full bigger size. To allow support of collects for REGSET_VARIABLE_SIZE we need two sizes. This is done by adding supply_size and collect_size. gdb/ * aarch64-fbsd-tdep.c (aarch64_fbsd_iterate_over_regset_sections): Add supply_size and collect_size. * aarch64-linux-tdep.c (aarch64_linux_iterate_over_regset_sections): Likewise. * alpha-linux-tdep.c (alpha_linux_iterate_over_regset_sections): * alpha-nbsd-tdep.c (alphanbsd_iterate_over_regset_sections): Likewise. * amd64-fbsd-tdep.c (amd64fbsd_iterate_over_regset_sections): Likewise. * amd64-linux-tdep.c (amd64_linux_iterate_over_regset_sections): Likewise. * arm-bsd-tdep.c (armbsd_iterate_over_regset_sections): Likewise. * arm-fbsd-tdep.c (arm_fbsd_iterate_over_regset_sections): Likewise. * arm-linux-tdep.c (arm_linux_iterate_over_regset_sections): Likewise. * corelow.c (get_core_registers_cb): Likewise.
