libjit/ChangeLog  view on Meta::CPAN

	* dpas/dpas-parser.y, dpas/dpas-types.c, dpas/dpas-types.h:
	report errors for unimplemented expressions and statements,
	so that users are not "surprised" when things silently fail.

	* .cvsignore, auto_gen.sh, configure.in, doc/.cvsignore,
	dpas/.cvsignore, dpas/Makefile.am, include/.cvsignore,
	jit/.cvsignore, jit/Makefile.am, jitdynamic/.cvsignore,
	jitdynamic/Makefile.am, jitplus/.cvsignore, jitplus/Makefile.am,
	tools/.cvsignore, tutorial/.cvsignore, tutorial/Makefile.am:
	modify the autoconf/automake build system to use libtool.

2004-05-10  Rhys Weatherley  <rweather@southern-storm.com.au>

	* jit/jit-reg-alloc.c, jit/jit-reg-alloc.h, jit/jit-rules-interp.c:
	interpreter code conversion for relative pointer and copy opcodes;
	fix some bugs in stack-based register allocation.

	* dpas/dpas-parser.y, dpas/dpas-types.c, dpas/dpas-types.h:
	loading and storing record fields in Dynamic Pascal.

Compiler notes
--------------

It is highly recommended that you build libjit with gcc and not
some other C compiler, even if you plan to use some other C
compiler to access the library.  We make use of a number of gcc
builtins to assist with stack walking, dynamic function calls,
and closures.

It is also recommended that you don't use the "-fomit-frame-pointer"
option when compiling programs that use libjit.  Otherwise stack walking
may not work correctly, leading to problems when throwing exceptions.
The configure script for libjit will detect the presence of this
option in CFLAGS and remove it when building libjit itself.
