From e6314db0ac537695a20feb5fab8d77a30836eccf Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Sun, 13 Mar 2011 19:24:26 +0000 Subject: gallivm: Use LLVM MC disassembler, instead of udis86. Included in LLVM 2.7+. Unlink udis86, should support all instructions that LLVM can emit. --- src/gallium/auxiliary/gallivm/lp_bld_debug.c | 141 --------------------------- 1 file changed, 141 deletions(-) delete mode 100644 src/gallium/auxiliary/gallivm/lp_bld_debug.c (limited to 'src/gallium/auxiliary/gallivm/lp_bld_debug.c') diff --git a/src/gallium/auxiliary/gallivm/lp_bld_debug.c b/src/gallium/auxiliary/gallivm/lp_bld_debug.c deleted file mode 100644 index 93e56553d7..0000000000 --- a/src/gallium/auxiliary/gallivm/lp_bld_debug.c +++ /dev/null @@ -1,141 +0,0 @@ -/************************************************************************** - * - * Copyright 2009 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 VMWARE 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. - * - **************************************************************************/ - - -#ifdef HAVE_UDIS86 -#include -#endif - -#include "util/u_math.h" -#include "util/u_debug.h" -#include "lp_bld_debug.h" - - -/** - * Check alignment. - * - * It is important that this check is not implemented as a macro or inlined - * function, as the compiler assumptions in respect to alignment of global - * and stack variables would often make the check a no op, defeating the - * whole purpose of the exercise. - */ -boolean -lp_check_alignment(const void *ptr, unsigned alignment) -{ - assert(util_is_power_of_two(alignment)); - return ((uintptr_t)ptr & (alignment - 1)) == 0; -} - - -void -lp_disassemble(const void* func) -{ -#ifdef HAVE_UDIS86 - ud_t ud_obj; - uint64_t max_jmp_pc; - uint inst_no; - boolean emit_addrs = TRUE, emit_line_nos = FALSE; - - ud_init(&ud_obj); - - ud_set_input_buffer(&ud_obj, (void*)func, 0xffff); - - max_jmp_pc = (uint64_t) (uintptr_t) func; - ud_set_pc(&ud_obj, max_jmp_pc); - -#ifdef PIPE_ARCH_X86 - ud_set_mode(&ud_obj, 32); -#endif -#ifdef PIPE_ARCH_X86_64 - ud_set_mode(&ud_obj, 64); -#endif - - ud_set_syntax(&ud_obj, UD_SYN_ATT); - - while (ud_disassemble(&ud_obj)) { - - if (emit_addrs) { -#ifdef PIPE_ARCH_X86 - debug_printf("0x%08lx:\t", (unsigned long)ud_insn_off(&ud_obj)); -#endif -#ifdef PIPE_ARCH_X86_64 - debug_printf("0x%016llx:\t", (unsigned long long)ud_insn_off(&ud_obj)); -#endif - } - else if (emit_line_nos) { - debug_printf("%6d:\t", inst_no); - inst_no++; - } -#if 0 - debug_printf("%-16s ", ud_insn_hex(&ud_obj)); -#endif - - debug_printf("%s\n", ud_insn_asm(&ud_obj)); - - if(ud_obj.mnemonic != UD_Icall) { - unsigned i; - for(i = 0; i < 3; ++i) { - const struct ud_operand *op = &ud_obj.operand[i]; - if (op->type == UD_OP_JIMM){ - uint64_t pc = ud_obj.pc; - - switch (op->size) { - case 8: - pc += op->lval.sbyte; - break; - case 16: - pc += op->lval.sword; - break; - case 32: - pc += op->lval.sdword; - break; - default: - break; - } - if(pc > max_jmp_pc) - max_jmp_pc = pc; - } - } - } - - if (ud_obj.mnemonic == UD_Iinvalid || - (ud_insn_off(&ud_obj) >= max_jmp_pc && - (ud_obj.mnemonic == UD_Iret || - ud_obj.mnemonic == UD_Ijmp))) - break; - } - -#if 0 - /* Print GDB command, useful to verify udis86 output */ - debug_printf("disassemble %p %p\n", func, (void*)(uintptr_t)ud_obj.pc); -#endif - - debug_printf("\n"); -#else - (void)func; -#endif -} -- cgit v1.2.3
