When testing my Solaris < 10 removal patch on Solaris/SPARC, I found that gdb mainline is currently broken there due to the recent SPARC M7 ADI patches: /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:1876:0: error: "PSR_ICC" redefined [-Werror] #define PSR_ICC 0x00f00000 ^ In file included from /usr/include/v7/sys/privregs.h:24:0, from /usr/include/sys/regset.h:420, from /usr/include/sys/ucontext.h:21, from /usr/include/sys/signal.h:231, from /usr/include/sys/procset.h:23, from /usr/include/sys/wait.h:25, from /usr/include/stdlib.h:21, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb/local/gdb/common/common-defs.h:53, from /vol/src/gnu/gdb/gdb/local/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:20: /usr/include/v7/sys/psr.h:35:0: note: this is the location of the previous definition #define PSR_ICC 0x00F00000 /* integer condition codes */ ^ /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:1878:0: error: "PSR_IMPL" redefined [-Werror] #define PSR_IMPL 0xf0000000 ^ In file included from /usr/include/v7/sys/privregs.h:24:0, from /usr/include/sys/regset.h:420, from /usr/include/sys/ucontext.h:21, from /usr/include/sys/signal.h:231, from /usr/include/sys/procset.h:23, from /usr/include/sys/wait.h:25, from /usr/include/stdlib.h:21, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb/local/gdb/common/common-defs.h:53, from /vol/src/gnu/gdb/gdb/local/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:20: /usr/include/v7/sys/psr.h:41:0: note: this is the location of the previous definition #define PSR_IMPL 0xF0000000 /* implementation */ ^ Comparing Solaris 11.4 <v7/sys/psr.h> and sparc64-tdep.c, there are more inconsistencies: <v7/sys/psr.h>: #define PSR_S 0x00000080 /* supervisor mode */ #define PSR_ICC 0x00F00000 /* integer condition codes */ #define PSR_VER 0x0F000000 /* mask version */ #define PSR_IMPL 0xF0000000 /* implementation */ #define PSR_RSV 0x000FC000 /* reserved */ sparc64-tdep.c: #define PSR_S 0x00000080 #define PSR_ICC 0x00f00000 #define PSR_VERS 0x0f000000 #define PSR_IMPL 0xf0000000 #define PSR_V8PLUS 0xff000000 #define PSR_XCC 0x000f0000 Apart from the capitalization differences that trip g++, the names differ (PSR_VER vs. PSR_VERS), PSR_XCC is included in Solaris' PSR_RSV, and there's no PSR_V8PLUS on Solaris either. /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c: In function `int adi_tag_fd()': /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:296:63: error: format `%d' expects argument of type `int', but argument 4 has type `pid_t {aka long int}' [-Werror=format=] snprintf (cl_name, sizeof(cl_name), "/proc/%d/adi/tags", pid); ^ /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c: In function `bool adi_is_addr_mapped(CORE_ADDR, std::size_t)': /vol/src/gnu/gdb/gdb/local/gdb/sparc64-tdep.c:314:64: error: format `%d' expects argument of type `int', but argument 4 has type `pid_t {aka long int}' [-Werror=format=] snprintf (filename, sizeof filename, "/proc/%d/adi/maps", pid); ^ You cannot always print a pid_t, which can be either int or long on Solaris, as an int. Obviously, the ADI patch which modifies code shared between all SPARC targets, hasn't been tested on anything but Linux/SPARC. The patch below includes the minimal fixes necessary to unbreak the Solaris/SPARC build. However, as detailed in the PR, there's more breakage here: apart from not bothering to implement ADI support on Solaris, the code contains several more changes to shared/common SPARC code that are simply wrong on anything but Linux/SPARC. The patch was tested on sparcv9-sun-solaris2.10 and sparcv9-sun-solaris2.11.4 (build and gdb/gdb gdb/gdb smoke test only). PR build/22206 * sparc64-tdep.c (adi_tag_fd): Print pid as long. (adi_is_addr_mapped): Likewise. (PSR_ICC): Don't redefine. (PSR_IMPL): Likewise. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
