2012-12-02 Paulo Andrade <pcpa@gnu.org> * tests/Makefile.am, tests/3to2.c, tests/3to2.ok, tests/add.c, tests/add.ok, tests/allocai.c, tests/allocai.ok, tests/bp.c, tests/bp.ok, tests/divi.c, tests/divi.ok, tests/fib.c, tests/fib.ok, tests/fibdelay.c, tests/fibdelay.ok, tests/fibit.c, tests/fibit.ok, tests/funcfp.c, tests/funcfp.ok, tests/incr.c, tests/incr.ok, tests/ldst.c, tests/ldst.ok, tests/ldxi.c, tests/ldxi.ok, tests/modi.c, tests/modi.ok, tests/movi.c, tests/movi.ok, tests/printf.c, tests/printf.ok, tests/printf2.c, tests/printf2.ok, tests/ret.c, tests/ret.ok, tests/rpn.c, tests/rpn.ok, tests/rpnfp.c, tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c, tests/testfp.ok, tests-run-test: Removed previous test suite, in favor of a newer one in the check subdirectory. * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst, check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst, check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst: New sample input for the new test program, loosely matching several of the previous test cases. * check/Makefile.am: New test suite makefile. * check/check.sh, check/run-test: New wrapper files for the new test suite. * check/lightning.c: New file. The main driver of the new test suite, that compiles to a parser of a very simple assembly like language, generates jit and executes it. * check/all.tst: New file. A generic debug and sample test file with a directive to prevent it from being executed, and useful to read disassembly of all possible instructions, using a fixed set of registers. * include/Makefile.am, include/lightning.h, include/lightning/Makefile.am, include/lightning/jit_arm.h, include/lightning/jit_mips.h, include/lightning/jit_ppc.h, include/lightning/jit_private.h, include/lightning/jit_x86.h, lib/Makefile.am, lib/jit_disasm.c, lib/jit_print.c, lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c, lib/jit_x86.c, lib/lightning.c: New files. These files are written from scratch, only by <pcpa@gnu.org>, and have now copyright assignment to the FSF. This is the core of the new lightning rework. Previously it was integrated in code with a garbage collector and several custom types like vectors and hash tables, so this first code merge with lightning converts that code into a library extracting only the jit bits, and at first only for x86_64 GNU/Linux. * lightning.h, m4/lightning.m4: Removed. These are no longer required in the new lightning code. .gitignore, Makefile.am, configure.ac: Update for the new lightning code.
