gdb/ChangeLog: Update copyright year range in all GDB files.
2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-03-22AArch64: gdbserver: read pauth registersAlan Hayward1-0/+1
Add the pauth registers to the regset lists. Add a new regset type OPTIONAL_REGS which allows for the regset read to fail. Once the read fails, it will not be checked again. This allows targets with optional features to keep a single static regset_info structure. gdb/ChangeLog: * arch/aarch64.h (AARCH64_PAUTH_REGS_SIZE): New define. gdb/gdbserver/ChangeLog: * linux-aarch64-low.c (aarch64_store_pauthregset): New function. * linux-low.c (regsets_store_inferior_registers): Allow optional reads to fail. * linux-low.h (enum regset_type): Add OPTIONAL_REGS.
2019-03-22AArch64: Read pauth registersAlan Hayward1-0/+3
Initialise the pauth registers when creating a target description, and store the regnum of the first pauth register. Use ptrace to read the registers in the pauth feature. Do not allow the registers to be written. gdb/ChangeLog: * aarch64-linux-nat.c (fetch_pauth_masks_from_thread): New function. (aarch64_linux_nat_target::fetch_registers): Read pauth registers. * aarch64-tdep.c (aarch64_cannot_store_register): New function. (aarch64_gdbarch_init): Add puth registers. * aarch64-tdep.h (struct gdbarch_tdep): Add pauth features. * arch/aarch64.h (AARCH64_PAUTH_DMASK_REGNUM): New define. (AARCH64_PAUTH_CMASK_REGNUM): Likewise.
2019-03-22AArch64: Add pointer authentication featureAlan Hayward1-2/+3
Pointer Authentication is a new feature in AArch64 v8.3-a. When enabled in the compiler, function return addresses will be mangled by the kernel. Add register description xml and wire up to aarch64_linux_read_description. This description includes the two pauth user registers. Nothing yet uses the feature - that is added in later patches. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Add pauth param. * aarch64-linux-tdep.c (aarch64_linux_core_read_description): Likewise. * aarch64-tdep.c (struct target_desc): Add in pauth.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+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.

2018-06-06Guard declarations of 'sve_{vq,vl}_from_{vl,vq}' macros on Aarch64 (and ↵Sergio Durigan Junior1-0/+4
unbreak build) Commit 122394f1476b1c925a281b15399119500c8231c1 ("Function for reading the Aarch64 SVE vector length") has added macros to manipulate SVE vector sizes based on Linux kernel sources, but did not guard them with #ifndef's, which breaks the build when the system headers already have these macros: CXX aarch64-linux-nat.o In file included from ../../gdb/aarch64-tdep.h:25, from ../../gdb/aarch64-linux-nat.c:30: ../../gdb/arch/aarch64.h:79: error: "sve_vq_from_vl" redefined [-Werror] #define sve_vq_from_vl(vl) ((vl) / 0x10) In file included from /usr/include/bits/sigcontext.h:30, from /usr/include/signal.h:291, from build-gnulib/import/signal.h:52, from ../../gdb/linux-nat.h:23, from ../../gdb/aarch64-linux-nat.c:26: /usr/include/asm/sigcontext.h:154: note: this is the location of the previous definition #define sve_vq_from_vl(vl) ((vl) / SVE_VQ_BYTES) In file included from ../../gdb/aarch64-tdep.h:25, from ../../gdb/aarch64-linux-nat.c:30: ../../gdb/arch/aarch64.h:80: error: "sve_vl_from_vq" redefined [-Werror] #define sve_vl_from_vq(vq) ((vq) * 0x10) In file included from /usr/include/bits/sigcontext.h:30, from /usr/include/signal.h:291, from build-gnulib/import/signal.h:52, from ../../gdb/linux-nat.h:23, from ../../gdb/aarch64-linux-nat.c:26: /usr/include/asm/sigcontext.h:155: note: this is the location of the previous definition #define sve_vl_from_vq(vq) ((vq) * SVE_VQ_BYTES) In order to fix this breakage, this commit guards the declaration of the macros using #ifndef's. gdb/ChangeLog: 2018-06-06 Sergio Durigan Junior <sergiodj@redhat.com> * arch/aarch64.h (sve_vg_from_vl): Guard with #ifndef.

2018-06-04Use uint64_t for SVE VQAlan Hayward1-1/+1
Previously VQ was of type long. Using uint64_t ensures it always matches the same type as the VG register. Note that in the Linux kernel, VQ is 16bits. We cast it up to 64bits immediately after reading to ensure we always use the same type throughout the code. gdb/ * aarch64-tdep.c (aarch64_read_description): Use uint64_t for VQ. * aarch64-tdep.h (aarch64_read_description): Likewise. * arch/aarch64.c (aarch64_create_target_description): Likewise. * arch/aarch64.h (aarch64_create_target_description): Likewise. * features/aarch64-sve.c (create_feature_aarch64_sve): Likewise. * nat/aarch64-sve-linux-ptrace.c(aarch64_sve_get_vq): Likewise. * nat/aarch64-sve-linux-ptrace.h (aarch64_sve_get_vq): Likewise.
2018-06-01Add SVE register definesAlan Hayward1-1/+14
In order to prevent gaps in the register numbering, the Z registers reuse the V register numbers (which become pseudos on SVE). 2018-06-01 Alan Hayward <alan.hayward@arm.com> * aarch64-tdep.c (aarch64_sve_register_names): New const var. * arch/aarch64.h (enum aarch64_regnum): Add SVE entries.
