Author: José Fonseca <[email protected]> Date: Wed Apr 24 13:08:46 2013 +0100 graw: Simple utilities to dump and disassemble TGSI tokens. Useful for core dumps, where calling tgsi_dump() from gdb is not an alternative. --- src/gallium/tests/graw/SConscript | 1 + src/gallium/tests/graw/disasm.c | 90 ++++++++++++++++++++++++++++++++++ src/gallium/tests/graw/tgsi_dump.gdb | 6 ++ 3 files changed, 97 insertions(+), 0 deletions(-) diff --git a/src/gallium/tests/graw/SConscript b/src/gallium/tests/graw/SConscript index 1fd2b53..8740ff3 100644 --- a/src/gallium/tests/graw/SConscript +++ b/src/gallium/tests/graw/SConscript @@ -16,6 +16,7 @@ if env['platform'] == 'freebsd8': progs = [ 'clear', + 'disasm', 'fs-fragcoord', 'fs-frontface', 'fs-test', diff --git a/src/gallium/tests/graw/disasm.c b/src/gallium/tests/graw/disasm.c new file mode 100644 index 0000000..0eef8cf --- /dev/null +++ b/src/gallium/tests/graw/disasm.c @@ -0,0 +1,90 @@ +/************************************************************************** + * + * Copyright 2013 VMware, Inc. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sub license, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice (including the + * next paragraph) shall be included in all copies or substantial portions + * of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. + * IN NO EVENT SHALL THE AUTHOR AND/OR ITS SUPPLIERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + * + **************************************************************************/ + + +/* + * Small utility to disassemble a memory dump of TGSI tokens. + * + * Dump can be easily obtained from gdb through the tgsi_dump.gdb helper: + * + * (gdb) source tgsi_dump.gdb + * (gdb) tgsi_dump state->tokens + * + * which will generate a tgsi_dump.bin file in the current directory. + */ + + +#include <stdio.h> +#include <stdlib.h> + +#include "pipe/p_shader_tokens.h" +#include "tgsi/tgsi_dump.h" + + +static void +usage(const char *arg0) +{ + fprintf(stderr, "usage: %s [ options ] <tgsi_dump.bin> ...\n", arg0); +} + + +static void +disasm(const char *filename) +{ + FILE *fp; + const size_t max_tokens = 1024*1024; + struct tgsi_token *tokens; + + fp = fopen(filename, "rb"); + if (!fp) { + exit(1); + } + tokens = malloc(max_tokens * sizeof *tokens); + fread(tokens, sizeof *tokens, max_tokens, fp); + + tgsi_dump(tokens, 0); + + free(tokens); + fclose(fp); +} + + +int main( int argc, char *argv[] ) +{ + int i; + + if (argc < 2) { + usage(argv[0]); + return 0; + } + + for (i = 1; i < argc; ++i) { + disasm(argv[i]); + } + + return 0; +} diff --git a/src/gallium/tests/graw/tgsi_dump.gdb b/src/gallium/tests/graw/tgsi_dump.gdb new file mode 100644 index 0000000..ab294d1 --- /dev/null +++ b/src/gallium/tests/graw/tgsi_dump.gdb @@ -0,0 +1,6 @@ +define tgsi_dump + set $tokens=(const struct tgsi_header *)$arg0 + set $nr_tokens = $tokens->HeaderSize + $tokens->BodySize + set $tokens_end = &tokens[$nr_tokens] + dump memory tgsi_dump.bin $tokens $tokens_end +end _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
