From e427fdff0af907faec8771b98e9cabeaadd05f12 Mon Sep 17 00:00:00 2001 From: Aaron Patterson Date: Fri, 22 Jan 2021 10:43:26 -0800 Subject: Directly link libcapstone for easier development This lets us use libcapstone directly from miniruby so we don't need a Ruby Gem to to dev work. Example usage: ```ruby def foo(x) if x < 1 "wow" else "neat" end end iseq = RubyVM::InstructionSequence.of(method(:foo)) puts UJIT.disasm(iseq) 100.times { foo 1 } puts UJIT.disasm(iseq) ``` Then in the terminal ``` $ ./miniruby test.rb == disasm: # (catch: FALSE) local table (size: 1, argc: 1 [opts: 0, rest: -1, post: 0, block: -1, kw: -1@-1, kwrest: -1]) [ 1] x@0 0000 getlocal_WC_0 x@0 ( 2)[LiCa] 0002 putobject_INT2FIX_1_ 0003 opt_lt 0005 branchunless 10 0007 putstring "wow" ( 3)[Li] 0009 leave ( 7)[Re] 0010 putstring "neat" ( 5)[Li] 0012 leave ( 7)[Re] == ISEQ RANGE: 10 -> 10 ======================================================== 0x0: movabs rax, 0x7fe816e2d1a0 0xa: mov qword ptr [rdi], rax 0xd: mov r8, rax 0x10: mov r9, rax 0x13: mov r11, r12 0x16: jmp qword ptr [rax] == ISEQ RANGE: 0 -> 7 ========================================================== 0x0: mov rax, qword ptr [rdi + 0x20] 0x4: mov rax, qword ptr [rax - 0x18] 0x8: mov qword ptr [rdx], rax 0xb: mov qword ptr [rdx + 8], 3 0x13: movabs rax, 0x7fe817808200 0x1d: test byte ptr [rax + 0x3e6], 1 0x24: jne 0x3ffff7b 0x2a: test byte ptr [rdx], 1 0x2d: je 0x3ffff7b 0x33: test byte ptr [rdx + 8], 1 0x37: je 0x3ffff7b 0x3d: mov rax, qword ptr [rdx] 0x40: cmp rax, qword ptr [rdx + 8] 0x44: movabs rax, 0 0x4e: movabs rcx, 0x14 0x58: cmovl rax, rcx 0x5c: mov qword ptr [rdx], rax 0x5f: test qword ptr [rdx], -9 0x66: jne 0x3ffffd5 ``` Make sure to `brew install pkg-config capstone` --- common.mk | 2 ++ 1 file changed, 2 insertions(+) (limited to 'common.mk') diff --git a/common.mk b/common.mk index 9cab62b60a..73f4c57473 100644 --- a/common.mk +++ b/common.mk @@ -1063,6 +1063,7 @@ BUILTIN_RB_SRCS = \ $(srcdir)/nilclass.rb \ $(srcdir)/prelude.rb \ $(srcdir)/gem_prelude.rb \ + $(srcdir)/ujit.rb \ $(empty) BUILTIN_RB_INCS = $(BUILTIN_RB_SRCS:.rb=.rbinc) @@ -15641,6 +15642,7 @@ ujit_core.$(OBJEXT): {$(VPATH)}vm_core.h ujit_core.$(OBJEXT): {$(VPATH)}vm_debug.h ujit_core.$(OBJEXT): {$(VPATH)}vm_opts.h ujit_core.$(OBJEXT): {$(VPATH)}vm_sync.h +ujit_iface.$(OBJEXT): {$(VPATH)}ujit.rbinc ujit_iface.$(OBJEXT): $(CCAN_DIR)/check_type/check_type.h ujit_iface.$(OBJEXT): $(CCAN_DIR)/container_of/container_of.h ujit_iface.$(OBJEXT): $(CCAN_DIR)/list/list.h -- cgit v1.2.3
