Extend SystemTap SDT probe argument parser 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).

direct access. It also takes into consideration the fact that some
registers are named differently inside and outside GDB, e.g., PPC's

Extend SystemTap SDT probe argument parser 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).

/* Getting rid of the register indirection suffix. */
Extend SystemTap SDT probe argument parser 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).

More invalid pointer to pointer conversions. As a follow up to: http://sourceware.org/ml/gdb-patches/2013-03/msg00449.html In a nutshell, casts between 'char **' <-> 'unsigned char **' and 'char **' <-> 'const char **' are invalid. I grepped for "\*\*) &" and found these. There's another one in demangle.c, but I've split fixing that one to a separate patch. I think the ada_decode_symbol change is perhaps the one that could be surprising. The function's description has this comment, which makes things much clearer: The GSYMBOL parameter is "mutable" in the C++ sense: logically const, but nevertheless modified to a semantically equivalent form when a decoded name is cached in it. */ const char * ada_decode_symbol (const struct general_symbol_info *gsymbol) With that out of the way, I think the patch ends up being pretty obvious. Tested on x86_64 Fedora 17. gdb/ 2013-03-13 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_decode_symbol): Cast away constness of GSYMBOL rather than casting 'const char * const *' to 'const char **'. * ada-lex.l (processInt): Make "trailer" local const. Remove 'const char **' cast. * arm-linux-tdep.c (arm_stap_parse_special_token): Add 'char *' locals, and use those as strtol output pointer, instead than doing invalid casts to from 'const char **' to 'char **'. (_initialize_demangle): Remove cast. * i386-tdep.c (i386_stap_parse_special_token): : Add 'char *' locals, and use those as strtol output pointer, instead than doing invalid casts to from 'const char **' to 'char **'. * solib-dsbt.c (dsbt_get_initial_loadmaps): Remove 'gdb_byte**' casts. * stap-probe.c (stap_parse_register_operand) (stap_parse_single_operand): Likewise.

Extend SystemTap SDT probe argument parser 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.

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).

Extend SystemTap SDT probe argument parser 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).

Extend SystemTap SDT probe argument parser 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).

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner. Tested on x86_64 and 32-bit ARM. 2013-12-11 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Pass selected frame to get_probe_argument_count and evaluate_probe_argument. * probe.c (get_probe_argument_count): Adjust declaration to accept frame.

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner.

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner. Tested on x86_64 and 32-bit ARM. 2013-12-11 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Pass selected frame to get_probe_argument_count and evaluate_probe_argument. * probe.c (get_probe_argument_count): Adjust declaration to accept frame.

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner. Tested on x86_64 and 32-bit ARM. 2013-12-11 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Pass selected frame to get_probe_argument_count and evaluate_probe_argument. * probe.c (get_probe_argument_count): Adjust declaration to accept frame.

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner.

remove some sym_probe_fns methods While looking into the probe API, it seemed to me that there were a number of methods in sym_probe_fns that were not needed. This patch removes them. Specifically, it seems to me that sym_probe_fns ought to be concerned with the API for constructing the probes. Any method relating to some aspect of an individual probe can be handled via the probe's own vtable. That is, the double indirection here doesn't seem useful -- it certainly isn't in fact used, but also I couldn't think of a potential use. 2013-12-06 Tom Tromey <tromey@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use get_probe_argument_count and evaluate_probe_argument. * elfread.c (elf_get_probe_argument_count) (elf_can_evaluate_probe_arguments, elf_evaluate_probe_argument) (elf_compile_to_ax): Remove.
