Yao Qi	8a81c5d7a7	Delete reinsert breakpoints from forked child When a thread is stepping over a syscall instruction with software single step, GDBserver inserts reinsert breakpoints at the next pcs. If the syscall call is fork, the forked child has reinsert breakpoint in its space, and GDBserver clones parent's breakpoint list to child's. When GDBserver resumes the child, its bp_reinsert is zero, but has reinsert breakpoints, so the following assert is triggered if I apply the patch extending step-over-syscall.exp. gdb/gdbserver/linux-low.c:4292: A problem internal to GDBserver has been detected.^M void linux_resume_one_lwp_throw(lwp_info, int, int, siginfo_t): Assertion `!has_reinsert_breakpoints (proc)' failed. gdb/gdbserver: 2016-06-17 Yao Qi <yao.qi@linaro.org> * linux-low.c (handle_extended_wait): If the parent is doing step-over, remove the reinsert breakpoints from the forked child.	10 years ago
Yao Qi	f50bf8e515	Step over exit with reinsert breakpoints This patch fixes a GDBserver crash when one thread is stepping over a syscall instruction which is exit. Step-over isn't finished due to the exit, but GDBserver doesn't clean up the state of step-over, so in the wait next time, GDBserver will wait on step_over_bkpt, which is already exited, and GDBserver crashes because 'requested_child' is NULL.

It also adds support for three new v9m hyperprivileged registers: %hmcdper, %hmcddfr and %hva_mask_nz.

Jose E. Marchesi	7a10c22feb	opcodes,gas: adjust sparc insns and make GAS aware of it This patch marks the SPARC instructions in the opcodes table with their proper opcode architectures, and makes the assembler aware of them. This allows the assembler to properly realize when a new instruction needs a higher architecture (after v9b) and to react accordingly emitting an error message or bumping the architecture. It also expands architecture mismatch tests to cover architectures higher than v9b, and fixes a couple of minor bugs in the GAS testsuite. opcodes/ChangeLog: 2016-06-17 Jose E.

Jose E. Marchesi	8b8c7c9f49	gas: sparc: fix collision of registers and pseudo-ops. The current sparc assembler breaks when the name of an ancillary-state register, privileged register or hyperprivileged register has a %-pseudo-operation name as a prefix. For example, %hmcdper and %hm(), or %hintp and %hi(). This patch fixes it by introducing a new table `perc_table' (for %-table) that contains an entry for every %name supported by the assembler, other than the general registers. This table is used to detect name collisions when the assembler tries to detect a %-pseudo-op. This patch also fixes a related bug, making sure that v9a_asr_table and hpriv_reg_table are sorted in reverse lexicographic order, as otherwise the search code may fail. gas/ChangeLog: 2016-06-17 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (priv_reg_table): Use NULL instead of the empty string to mark the end of the array. (hpriv_reg_table): Likewise. (v9a_asr_table): Likewise.

Jose E. Marchesi	4f26fb3a1b	bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine numbers. This patch adds support for the opcode architectures SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}. Note that for arches up to v9b (UltraSPARC III), the detection of the BFD machine type was based on the bits in the e_machine field of the ELF header. However, there are no more available bits in that field, so this patch takes the approach of using the hardware capabilities stored in the object attributes HWCAPS/HWCAPS2 in order to characterize the machine the object was built for. bfd/ChangeLog: 2016-06-17 Jose E.

Graham Markall	28215275a6	[ARC] Add ldbit for nps This commit adds the ldbit instruction for the NPS-400.

Andrew Burgess	cad8e26d2a	gdb: Use UNSUPPORTED not XFAIL for unsupported target features If a target does not support making function calls from GDB then in a number of test files, we currently report an XFAIL and skip some, or all of the tests. This commit changes the XFAIL to an UNSUPPORTED as this seems more appropriate in these cases. Some of the tests used bug ID 2416 to be reported in the XFAIL.
