Peter Johnson	aa3e6ff9b9	Change some optimization settings so that imm8 optimizations actually get triggered for more cases and optimize from 64-bit down to 32-bit for 64-bit mov instructions. This change means that mov reg64, constant will be auto-sized up to 64 bits, but mov reg64, expr/symbol will default to 32 bits. You must use mov reg64, qword expr/symbol if you need 64 bits, or in GAS mode use movabsq expr/symbol, reg64. This makes the generated code smaller and default most usages into 32-bit relocations appropriate for ELF64 and Win64. Right now, 32-bit unsigned relocs are generated instead of 32-bit signed; this will need to be fixed. * x86arch.h (x86_insn.postop): Add X86_POSTOP_SIGNEXT_IMM32. * x86bc.c (x86_bc_insn_resolve): Implement. * x86id.re (OPAP_SImm32Avail): New flag. (MOD_Op2AddSp): New modifier to encode spare directly into 2nd opcode byte. (arith_insn): Use MOD_Op2AddSp and add forced-size override forms. (mov_insn): Use OPAP_SImm32Avail and add forced-size override form. (yasm_x86__finalize_insn): Implement new flag and modifier. Fix up testcases for changes. svn path=/trunk/yasm/; revision=1314	19 years ago
Michael Urman	2c6d4e60dc	Implement global constants in elf. Add test to ensure they work; modify another test such that linked together they verify that 1. It links properly 2. The constant is loaded properly 3. The function is called properly shown (probably not proved) by the program exiting with error level 0. svn path=/trunk/yasm/; revision=1024	21 years ago
Michael Urman	7adc41bfab	Actually use provided relocation type, instead of feeble-minded guessing. Add test case that centers on relocations; update test case that uses them. svn path=/trunk/yasm/; revision=1023	21 years ago
Peter Johnson	6960b31329	Add Win32 object format (untested, but compared against NASM output). svn path=/trunk/yasm/; revision=884	22 years ago
Peter Johnson	50d92d758e	Fix COFF_SET_VMA output (needed to add section start address to addend). To ensure all section start addresses are known, added a first pre-pass of sections to calculate each one's address. svn path=/trunk/yasm/; revision=775	22 years ago
Peter Johnson	8f9c7383ea	Add COFF object format (for DJGPP). No debugging support yet (need to design dbgfmt interface). svn path=/trunk/yasm/; revision=773	22 years ago
