An earlier message warns about this: "warning: Signal SIGTRAP does not exist on this system." - The testcase is crafted in a way that expects a pattern of the stopping signal message instead of a successful core file read message. The following patch fixes this by changing the old pattern to a more reasonable one, while still ignoring the fact that mingw32-based GDB does not record a SIGTRAP in a core file because it does not define it. gdb/testsuite/ 2014-11-18 Luis Machado <lgustavo@codesourcery.com> * gdb.reverse/break-precsave: Expect completion message for core file reads. * gdb.reverse/consecutive-precsave.exp: Likewise. * gdb.reverse/finish-precsave.exp: Likewise. * gdb.reverse/i386-precsave.exp: Likewise. * gdb.reverse/machinestate-precsave.exp: Likewise. * gdb.reverse/sigall-precsave.exp: Likewise. * gdb.reverse/solib-precsave.exp: Likewise. * gdb.reverse/step-precsave.exp: Likewise. * gdb.reverse/until-precsave.exp: Likewise. * gdb.reverse/watch-precsave.exp: Likewise.

2014-11-17[gdbserver/lynx] spurious failure to write in inferior memoryJoel Brobecker2-5/+12
We noticed the following error on ppc-lynx178, using just about any program: (gdb) tar remote mytarget:4444 Remote debugging using mytarget:4444 0x000100c8 in _start () (gdb) b try Breakpoint 1 at 0x10844: file try.adb, line 11. (gdb) cont Continuing. !!!-> Cannot remove breakpoints because program is no longer writable. !!!-> Further execution is probably impossible. Breakpoint 1, try () at try.adb:11 11 Local : Integer := 18; And, of course, trying to continue yielded the expected outcome: (gdb) c Continuing. warning: Error removing breakpoint 1 Cannot remove breakpoints because program is no longer writable. Further execution is probably impossible. It turns out that the problem is caused by an intentional test against a variable with an undefined value. After GDB receives notification of the inferior stopping, it tries to remove the breakpoint by sending a memory-write packet ("X10844,4:9 "). This leads us to lynx_write_memory, where it tries to split the memory-write into chunks of 4 bytes. And, in order to handle writes which are not aligned on word boundaries, we have the following code: if (skip > 0 || truncate > 0) /* We need to read the memory at this address in order to preserve the data that we are not overwriting. */ lynx_read_memory (addr, (unsigned char *) &buf, xfer_size); if (errno) return errno; (the comment explains what the code is about). Unfortunately, the not-so-glaring error that we've made here is that we're checking ERRNO regardless of whether we've called lynx_read_memory. In our case, because we are writing 4 bytes aligned on a word boundary, we do not call lynx_read_memory and therefore test an ERRNO with an undefined value. gdb/gdbserver/ChangeLog: * lynx-low.c (lynx_write_memory): Put lynx_read_memory and corresponding ERRNO check in same block.

2014-11-14common-defs.h: include <stdarg.h> before <stdio.h>Joel Brobecker2-1/+6
When trying to build gdbserver on ppc-lynx178, the compiler reports while trying to compile gdbserver/ax.c that vsprintf is not declared. Looking at my C99 reference manual (a draft), I see the following synopsis: #include <stdarg.h> #include <stdio.h> int vsprintf(char * restrict s, [etc]); Looking at stdio.h on LynxOS-178, if found where vsprintf gets declared: #if defined(__varargs_h) || defined(__stdarg_h) \ || defined(_VARARGS_H) || defined(_STDARG_H) extern int vsprintf _AP((char *, const char *, va_list)); #endif Digging further, I noticed that common-defs.h, which is included via server.h, includes stdarg.h after including stdio, explaining why vsprintf does not get declared in this case. This patch fixes the problem by including stdarg.h before stdio.h. gdb/ChangeLog: * common/common-defs.h: Move <stdarg.h> #include ahead of <stdio.h> #include. Tested on x86_64-linux.

2014-11-14handle 'iconv's that define EILSEQ to ENOENTPedro Alves2-10/+27
We're currently pulling gnulib's errno module as a dependency of some other module. That provides an errno.h that defines EILSEQ to a distinct value if the system's errno.h doesn't define it already. However, GNU iconv does this: /* Get errno declaration and values. */ #include <errno.h> /* Some systems, like SunOS 4, don't have EILSEQ. Some systems, like BSD/OS, have EILSEQ in a different header. On these systems, define EILSEQ ourselves. */ #ifndef EILSEQ #define EILSEQ @EILSEQ@ #endif That's in: http://git.savannah.gnu.org/cgit/libiconv.git/tree/include/iconv.h.in The "different header" mentioned is wchar.h. This is handled in: http://git.savannah.gnu.org/cgit/libiconv.git/tree/m4/eilseq.m4 which defines @EILSEQ@ to ENOENT if EILSEQ isn't found in either errno.h or wchar.h. So if iconv sets errno to EILSEQ on such system's, it's really setting it to ENOENT. And when we check for EILSEQ, we're checking for gnulib's value. The result is we won't detect the error correctly. As we dropped support for both SunOS 4 or old BSD/OS, maybe we don't need to care about the wchar.h issue anymore. Still, AFAICS, gnulib's m4/errno_h.m4 doesn't know that EILSEQ may be defined in wchar.h, and so on such systems, ISTM gnulib ends up defining an incompatible EILSEQ itself, but I think that should be fixed on the gnulib side, by making it extract the EILSEQ value out of the system's wchar.h, like GNU iconv does. So that leaves handling the case of gnulib making up a EILSEQ value, which we take as meaning the system really doesn't really define it, which will be the same systems GNU iconv sets errno to ENOENT instead of EILSEQ. Looking at glibc's iconv it seems that ENOENT is never used there. It seems it's safe to always treat ENOENT the same as EILSEQ. The current EILSEQ definition under PHONY_ICONV is obviously stale as gnulib garantees there's always a EILSEQ defined. Tested on x86_64 Fedora 20. gdb/ 2014-11-14 Pedro Alves <palves@redhat.com> * charset.c [PHONY_ICONV && !EILSEQ] (EILSEQ): Don't define. [!PHONY_ICONV] (gdb_iconv): New function.

The patch <https://sourceware.org/ml/gdb-patches/2014-03/msg00202.html> fixed dw2-ifort-parameter.exp on powerpc64 by adding some labels to get the start and end address of function func. This should also fix the fail on thumb mode, however, this style is quite specific to gcc, and other compiler, such as clang, may not guarantee the order of global asms and functions. The test fails with clang: $ make check RUNTESTFLAGS='dw2-ifort-parameter.exp CC_FOR_TARGET=clang' (gdb) p/x param^M No symbol "param" in current context.^M (gdb) FAIL: gdb.dwarf2/dw2-ifort-parameter.exp: p/x param With this patch applied, dw2-ifort-parameter.exp still passes for gcc on arm thumb mode and popwerpc64, and it also passes for clang on x86_linux. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/dw2-ifort-parameter.c: Remove inline asm. (func): Add label func_label. * gdb.dwarf2/dw2-ifort-parameter.exp (Dwarf::assemble): Replace low_pc and high_pc with MACRO_AT_range. Replace name, low_pc and high_pc with MACRO_AT_func.
2014-11-14Fix implptr-optimized-out.exp failYao Qi2-3/+8
Hi, I see the fail in gdb.dwarf2/implptr-optimized-out.exp in thumb mode (gdb) p p->f^M No symbol "p" in current context.^M (gdb) FAIL: gdb.dwarf2/implptr-optimized-out.exp: p p->f and the crash on powerpc64 (gdb) continue^M Continuing.^M ^M Program received signal SIGSEGV, Segmentation fault.^M 0x7d82100810000828 in ?? () The cause of both is that we incorrectly set attribute low_pc, since main isn't resolved to function start address on these targets. In this patch, we replace attributes name, low_pc and high_pc with MACRO_AT_func. The fail on thumb mode is fixed, and crash on powerpc64 is fixed too. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/implptr-optimized-out.exp (Dwarf::assemble): Replace name, low_pc and high_pc with MACRO_AT_func.

This patch is to use dwarf::assemble to generate debug information, and remove implptr-optimized-out.S as a result. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/implptr-optimized-out.exp: Use Dwarf::assemble to produce debug information. * gdb.dwarf2/implptr-optimized-out.S: Removed.
2014-11-14Get start and end address of main in dwz.expYao Qi3-57/+14
On arm-none-eabi target thumb mode, I see the following fail, p the_int^M $2 = 99^M (gdb) FAIL: gdb.dwarf2/dwz.exp: p the_int and on powerpc64 target, we even can't get function main from object file, disassemble main^M No function contains specified address.^M (gdb) FAIL: gdb.dwarf2/dwz.exp: disassemble main This patch is to use MACRO_AT_func attribute to get the main's start address and end address correctly, and also remove some code dwz.exp getting main's length. This patch fixes fails on both thumb mode and powerpc64 target. PASS: gdb.dwarf2/dwz.exp: p other_int PASS: gdb.dwarf2/dwz.exp: p the_int gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * gdb.dwarf2/dwz.exp: Remove the code to compile main.c to object and get function length. (Dwarf::assemble): Replace name, low_pc and high_pc attributes with MACRO_AT_func. (top-level): Replace gdb_compile and clean_restart with prepare_for_testing. * gdb.dwarf2/main.c (main): Add label main_label.
2014-11-14DW attribute macro MACRO_AT_func and MACRO_AT_rangeYao Qi2-6/+131
This patch addes DW macro attributes MACRO_AT_func and MACRO_AT_range in dwarf assembler, which emits "DW_AT_low_pc func_start addr" and "DW_AT_high_pc func_end addr". func_start and func_end are computed automatically by proc function_range. These two attributes are pseudo attribute or macro attribute, which means they are not standard dwarf attribute in dwarf spec. Then can be substituted or expanded to standard attributes or macro attributes. See details in the comments to them. Dwarf assembler is extended to handle them. Now the attributes name/low_pc/high_pc can be replaced with MACRO_AT_func like this: subprogram { {name main} {low_pc main_start addr} {high_pc main_end addr} } becomes: subprogram { {MACRO_AT_func { main ${srcdir}/${subdir}/${srcfile} }} } users don't have to worry about the start and end of function main, and they only need to add a label main_label in main. gdb/testsuite: 2014-11-14 Yao Qi <yao@codesourcery.com> * lib/dwarf.exp (function_range): New procedure. (Dwarf::_handle_macro_at_func): New procedure. (Dwarf::_handle_macro_at_range): New procedure. (Dwarf): Handle MACRO_AT_func and MACRO_AT_range.
