[Git][cmucl/cmucl][master] 2 commits: Fix #98: Use FSTP instruction with appropriate size

[Git][cmucl/cmucl][master] 2 commits: Fix #95: Fix disassembly for je and movzx/movsx instructions
by Raymond Toy 11 Jan '21

11 Jan '21

Raymond Toy pushed to branch master at cmucl / cmucl Commits: b5bfb153 by Raymond Toy at 2021-01-11T05:37:39+00:00 Fix #95: Fix disassembly for je and movzx/movsx instructions We were printing `jeq` for the branch on equal instruction, but it should be `je`. This is fixed by changing the order of the options in the `defconstant` `conditions`. The first in the list is the preferred value, so we can write `je`, `jeq`, or `jz`, but these will all get printed out as `je` instead of the previous `jeq`. For `movzx` and `movsx`, we need to specify the size of the memory object to match Intel syntax. This is done by changing the size of the `ext-reg-reg/mem` format so that the reg/mem field has type `sized-reg/mem` instead of just `reg/mem`. Finally, we just added a note that the `break` instruction is really the `int3` instruction. I don't know why it's called `break` instead of `int3`. - - - - - 5e87a39a by Raymond Toy at 2021-01-11T05:37:39+00:00 Merge branch 'issue-95-fix-disassem-syntax' into 'master' Fix #95: Fix disassembly for je and movzx/movsx instructions Closes #95 See merge request cmucl/cmucl!64 - - - - - 2 changed files: - src/bootfiles/21d/boot-2020-04-1.lisp - src/compiler/x86/insts.lisp Changes: ===================================== src/bootfiles/21d/boot-2020-04-1.lisp ===================================== @@ -10,3 +10,8 @@ ;; x86: cross-x86-x86 ;; sparc: cross-sparc-sparc +;; This is also used to easily change the order of x86::conditions +;; constant so that we prefer je instead of jeq.
