2013-12-28Extend handling of immediates on ARM's SystemTap SDT probe supportSergio Durigan Junior2-4/+11
Continuing my series of fixes on the SystemTap SDT support for the ARM/AArch64 architectures, this patch now extends how ARM's SDT specific parser handles literal numbers (immediates). Currently, it only accepts "#" as the prefix. However, according to "info '(as) ARM-Chars'", expressions can also have "$" and nothing as a prefix. This patch extends the parser to accept those options. 2013-12-28 Sergio Durigan Junior <sergiodj@redhat.com> * arm-linux-tdep.c (arm_stap_is_single_operand): Accept "$" as a literal prefix. Also accept no prefix at all. (arm_stap_parse_special_token): Likewise. (arm_linux_init_abi): Likewise.
2013-12-28Implement SystemTap SDT probe support for AArch64Sergio Durigan Junior3-0/+150
This commit implements the needed bits for SystemTap SDT probe support on AArch64 architectures. First, I started by looking at AArch64 assembly specification and filling the necessary options on gdbarch's stap machinery in order to make the generic asm parser (implemented in stap-probe.c) recognize AArch64's asm. After my last patch for the SystemTap SDT API, which extends it in order to accept multiple prefixes and suffixes, this patch became simpler. I also followed Marcus suggestion and did not shared code between 32- and 64-bit ARM. Tom asked me in a previous message how I did my tests. I believe I replied that, but just in case: I ran the tests on gdb.base/stap-probe.exp by hand. I also managed to run the tests on real hardware, and they pass without regressions. 2013-12-28 Sergio Durigan Junior <sergiodj@redhat.com> PR tdep/15653 * NEWS: Mention SystemTap SDT probe support for AArch64 GNU/Linux. * aarch64-linux-tdep.c: Include necessary headers for parsing of SystemTap SDT probes.

2013-12-19Extend SystemTap SDT probe argument parserSergio Durigan Junior11-208/+513
This patch extends the current generic parser for SystemTap SDT probe arguments. It can be almost considered a cleanup, but the main point of it is actually to allow the generic parser to accept multiple prefixes and suffixes for the its operands (i.e., integers, register names, and register indirection). I have chosen to implement this as a list of const strings, and declare this list as "static" inside each target's method used to initialize gdbarch. This patch is actually a preparation for an upcoming patch for ARM, which implements the support for multiple integer prefixes (as defined by ARM's asm spec). And AArch64 will also need this, for the same reason. This patch was regtested on all architectures that it touches (i.e., i386, x86_64, ARM, PPC/PPC64, s390x and IA-64). No regressions were found. 2013-12-19 Sergio Durigan Junior <sergiodj@redhat.com> * amd64-tdep.c (amd64_init_abi): Declare SystemTap SDT probe argument prefixes and suffixes.

2013-12-19Fix PR breakpoints/16297: catch syscall with syscall 0Gabriel Krisman Bertazi5-9/+43
Code rationale ============== by: Gabriel Krisman Bertazi This is a fix for bug 16297. The problem occurs when the user attempts to catch any syscall 0 (such as syscall read on Linux/x86_64). GDB was not able to catch the syscall and was missing the breakpoint. Now, breakpoint_hit_catch_syscall returns immediately when it finds the correct syscall number, avoiding a following check for the end of the search vector, that returns a no hit if the syscall number was zero. Testcase rationale ================== by: Sergio Durigan Junior This testcase is a little difficult to write. By doing a quick inspection at the Linux source, one can see that, in many targets, the syscall number 0 is restart_syscall, which is forbidden to be called from userspace. Therefore, on many targets, there's just no way to test this safely. My decision was to take the simpler route and just adds the "read" syscall on the default test. Its number on x86_64 is zero, which is "good enough" since many people here do their tests on x86_64 anyway and it is a popular architecture. However, there was another little gotcha. When using "read" passing 0 as the third parameter (i.e., asking it to read 0 bytes), current libc implementations could choose not to effectively call the syscall. Therefore, the best solution was to create a temporary pipe, write 1 byte into it, and then read this byte from it. gdb/ChangeLog 2013-12-19 Gabriel Krisman Bertazi <gabriel@krisman.be> PR breakpoints/16297 * breakpoint.c (breakpoint_hit_catch_syscall): Return immediately when expected syscall is hit. gdb/testsuite/ChangeLog 2013-12-19 Sergio Durigan Junior <sergiodj@redhat.com> PR breakpoints/16297 * gdb.base/catch-syscall.c (read_syscall, pipe_syscall) (write_syscall): New variables.

2013-12-19don't allocate serial_opsTom Tromey5-182/+226
Now that struct serial_ops is const everywhere, we can easily turn the instances into globals. This patch implements this idea. On the one hand I think this is nicer since it makes a bit more data readonly and slightly reduces allocations. On the other hand it reduces readability somewhat. If the readability is a concern to anyone I was thinking I could write a macro that conditionally uses GCC's designated initializer extension.

2013-12-19remove remnants of old Mach-O workaroundTom Tromey2-14/+13
I happened to run readelf on an ELF file created by Guile. readelf complained about invalid values for DW_FORM_strp. At first I assumed this was just a Guile bug, but eu-readelf did the right thing, so I looked a bit deeper. I came across some old Mach-O code to bias some offsets by section addresses. Guile, unlike many ELF writers, sets the address for the various DWARF-related sections, causing this unusual code to be run. This code came from an old commit: 2005-09-30 H.J.
