2014-05-16Copy file1.txt to remote host in dw2-filename.exp and dw2-anonymous-func.expYao Qi3-0/+17
Some gdb.dwarf2/*.exp tests copy file1.txt to host via gdb_remote_download but dw2-filename.exp and dw2-anonymous-func.exp don't do that. Looks like an oversight in this patch https://sourceware.org/ml/gdb-patches/2013-08/msg00365.html There are some fails in remote host testing. FAIL: gdb.dwarf2/dw2-anonymous-func.exp: list file1.txt FAIL: gdb.dwarf2/dw2-filename.exp: interpreter-exec mi -file-list-exec-source-files FAIL: gdb.dwarf2/dw2-filename.exp: info sources This patch is to invoke gdb_remote_download to copy file1.txt to host and remote it at the end. This patch fixes these fails above. gdb/testsuite: 2014-05-16 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/dw2-filename.exp: Copy file1.txt to host. Remove file1.txt from host at the end. * gdb.dwarf2/dw2-anonymous-func.exp: Likewise.
2014-05-16Fix display of tabulation character for mingw hosts.Yao Qi2-59/+70
Pierre proposed this patch https://sourceware.org/ml/gdb-patches/2013-10/msg00011.html and Tom gave a suggestion that it's better to do check \t in print_wchar <https://sourceware.org/ml/gdb-patches/2013-11/msg00148.html> However, I don't see the follow-up to this discussion. We encounter two fails in printcmds.exp on mingw host, and Pierre's patch fixes them. I pick it up, update a little per Tom's comments, and post it here for review. This patch fixes these fails below on mingw32 host. FAIL: gdb.base/charset.exp: print string in ASCII FAIL: gdb.base/charset.exp: try printing '\t' in ASCII FAIL: gdb.base/charset.exp: print string in ISO-8859-1 FAIL: gdb.base/charset.exp: try printing '\t' in ISO-8859-1 FAIL: gdb.base/charset.exp: print string in UTF-32 FAIL: gdb.base/charset.exp: try printing '\t' in UTF-32 FAIL: gdb.base/printcmds.exp: p ctable1[9] FAIL: gdb.base/printcmds.exp: p &ctable1[1*8] Also regression tested on x86_64-linux. Is it OK? gdb: 2014-05-16 Pierre Muller <muller@sourceware.org> Yao Qi <yao@codesourcery.com> * valprint.c (print_wchar): Move the code on checking whether W is a printable wide char to the default branch of switch statement below. Call wchar_printable instead of gdb_iswprint.

2014-05-15Make more robust when run in parallel mode.Doug Evans3-3/+18
Since we're not compiling with gcc, we don't know where the DWO file will ultimately be built. It could be built in testsuite/gdb.dwarf2/foo (non-parallel mode) or testsuite/outputs/gdb.dwarf2/foo (parallel mode). * gdb.dwarf2/fission-reread.S: Remove directory from .dwo file path. * gdb.dwarf2/fission-reread.exp: Set debug-file-directory before loading file.

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.
