2014-05-15Fix argument passing in mi_run_cmd_fullSimon Marchi2-1/+18
Passing arguments did not work when use_mi_command was set. gdb/testsuite/ChangeLog: 2014-05-13 Simon Marchi <simon.marchi@ericsson.com> * lib/mi-support.exp (mi_run_cmd_full): Set arguments by calling "-exec-arguments" or "set args" before running the inferior.

2014-05-14Fix mi-file.exp fails on remote hostYao Qi2-2/+13
This patch fixes mi-file.exp fails on remote host. First, we can't assume ${srcdir}/${subdir}/${srcfile} directory exists on remote host, so this patch changes it to match ${srcfile} only on remote host. Second, regexp pattern ".*/${srcfile}" isn't friendly to Windows path. The file name is "basics.c" in my test env and can't match the pattern due to "/" in it. Remove "/" from the pattern. gdb/testsuite: 2014-05-14 Yao Qi <yao@codesourcery.com> * gdb.mi/mi-file.exp (test_file_list_exec_source_file): Don't match absolute path on remote host. (test_file_list_exec_source_files): Remove "/" from the pattern.
2014-05-14Overwrite ${board}_file in local-remote-hostYao Qi2-0/+12
After I run test like this, $ make check RUNTESTFLAGS='--host_board=local-remote-host dw2-basic.exp' gdb.dwarf2/file1.txt in source tree was removed. In some gdb.dwarf2/*.exp, file1.txt is copied to host and then removed at the end. However, in local-remote-host-notty.exp, ${board}_download doesn't copy the file but return the absolute path of the src file. 'remote_file host delete' at the end will remove the file in source tree. This patch is to overwrite ${board}_file, and specially make "delete" option do nothing. This approach is used in gdbserver-base.exp and remote-stdio-gdbserver.exp too. gdb/testsuite: 2014-05-14 Yao Qi <yao@codesourcery.com> * boards/local-remote-host-notty.exp (${board}_file): New proc.

2014-05-13With -pie and x86, the linker complains if it sees a PC-relative relocationSriraman Tallam10-24/+86
to access a global as it expects a GOTPCREL relocation. This is really not necessary as the linker could use a copy relocation to get around it. This patch enables copy relocations with pie. Context: This is useful because currently the GCC compiler with option -fpie makes every extern global access go through the GOT. That is because the compiler cannot tell if a global will end up being defined in the executable or not and is conservative. This ends up hurting performance when the binary is linked as mostly static where most of the globals do end up being defined in the executable. By allowing copy relocs with fPIE, the compiler need not generate a GOTPCREL(GOT access) for any global access. It can safely assume that all globals will be defined in the executable and generate a PC-relative access instead. Gold can then create a copy reloc for only the undefined globals. gold/ * symtab.h (may_need_copy_reloc): Remove check for position independent code. * x86_64.cc (Target_x86_64<size>::Scan::global): Add check for no position independence before pc absolute may_need_copy_reloc call.

2014-05-12mi: Use the value in mi_console_file->quote as the quoting characterSimon Marchi2-3/+9
In mi_interpreter_init, multiple MI consoles/channels are created and a quoting character is given. In mi_console_raw_packet, we check if the value is not 0 to decide if we should quote the string, but we don't use the value. It is hardcoded to ". We might never use another quoting character than an actual quote, but I suggest we change it, for correctness. There is not visible behavior change. I changed the latest fputs_unfiltered changed to fputc_unfiltered just to stay consistent. gdb/ChangeLog: 2014-05-12 Simon Marchi <simon.marchi@ericsson.com> * mi/mi-console.c (mi_console_raw_packet): Use the value from mi_console->quote as the quoting character.

* mmo.c: Update URLs in documentation comments.
2014-05-08Add support for emulating the MSP430 hardware multiply feature.Nick Clifton2-23/+192
* msp430-sim.c (sim_open): Do not allocate memory over the hardware multiply registers. (get_op): Add support for reads from the hardware multiply registers. (put_op): Add support for writes to the hardware multiply registers. (msp430_step_once): Add support for the RETI instruction used by the CPUX architecture.
2014-05-08or1k: add support for l.swa/l.lwa atomic instructionsStefan Kristiansson8-49/+178
This adds support for the load-link/store-conditional l.lwa/l.swa atomic instructions. The support is added in such way, that the cpu description not only describes the mnemonics, but also the functionality. A couple of fixes to typos in nearby/related code are also snuck into this. cpu/ * or1korbis.cpu (h-atomic-reserve): New hardware. (h-atomic-address): Likewise. (insn-opcode): Add opcodes for LWA and SWA. (atomic-reserve): New operand. (atomic-address): Likewise. (l-lwa, l-swa): New instructions. (l-lbs): Fix typo in comment. (store-insn): Clear atomic reserve on store to atomic-address. Fix register names in fmt field. opcodes/ * or1k-desc.c: Regenerated. * or1k-desc.h: Likewise. * or1k-opc.c: Likewise. * or1k-opc.h: Likewise. * or1k-opinst.c: Likewise.
