From b768fab8b135a722a76dc26b2037d40cdbae9b35 Mon Sep 17 00:00:00 2001 From: pcpa Date: 2013年9月24日 03:31:54 -0300 Subject: Add code to calculate code buffer size based on devel time information. * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c: New files implementing static tables with longest known instructions length generated to match a lightning instruction. These tables should make it easier to make it very unlikely to ever miscalculate, or by too much, the size of a code buffer. * lib/jit_size.c: New file that aids to either collect jit code size information, or use the information depending on build options. * size.c: New helper file that parses input for, and create an initial jit_$arch-sz.c file, that needs some minor edit for arches with multiple configurations. * configure.ac, Makefile.am: Add the new, devel mode only --enable-devel-get-jit-size configure option, that sets compile time flags to collect jit code size information, that will be used as input for the "noinst size program". * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor changes for the --enable-devel-get-jit-size build mode, as well as the "production build mode" with jit code size information. --- lib/jit_disasm.c | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/jit_disasm.c') diff --git a/lib/jit_disasm.c b/lib/jit_disasm.c index af2cb52..00cd71c 100644 --- a/lib/jit_disasm.c +++ b/lib/jit_disasm.c @@ -225,6 +225,7 @@ disasm_print_address(bfd_vma addr, struct disassemble_info *info) (*info->fprintf_func)(info->stream, "0x%s", buffer); # define _jit disasm_jit +# undef jit_pointer_p # define jit_pointer_p(u) \ ((u)>= _jit->code.ptr && (u) < _jit->pc.uc) if (jit_pointer_p((jit_uint8_t *)(jit_word_t)addr)) { -- cgit v1.2.3
