2012-12-01 Paulo Andrade <pcpa@gnu.org> * opcode/Makefile.am, opcode/Makefile.in, opcode/ansidecl.h, opcode/bfd.h, opcode/dis-asm.h, opcode/dis-buf.c, opcode/disass.c, opcode/i386-dis.c, opcode/i386.h, opcode/ppc-dis.c, opcode/ppc-opc.c, opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h, opcode/sysdep.h: Removed. Do not bundle GNU binutils files. * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in, lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain autogenerated files that also generate too much diff noise when regenerated in git. * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi: Removed. Buildenvironment must have an up to date version from upstream installed. * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp, build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed. Do not maintain a copy of automake files in git. Release tarballs must use an up to date version. * lightningize.in, doc/lightningize.1: Removed. Do not encourage bundling lightning in other packages. It should use a system package or a proper thirdy part subdirectory. * INSTALL: Removed. Autoreconf removes it and creates a symlink when regenerating files, so, avoid conflicts in git and let automake create the symlink. * .gitignore: Add INSTALL and autogenerated files. * configure.ac, Makefile.am: Update for removal of opcode subdir, auto generated files and lightningize. * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c: Update for removal of opcode subdir. * doc/Makefile.am: Update for removal of lightningize. * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h, lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h, tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c: Remove LIGHTNING_CROSS, it is half supported and incomplete. * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor check on JIT_FPR. If no hardware registers are available, the backend must provide an alternative for software float. * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am: Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement properly on some backends due to stack alignment constraints, and whenever it is required, using jit_allocai and using a properly aligned stack vector, or a heap buffer, is better. * tests/push-pop.c, tests/push-pop.ok: Removed due to JIT_NEED_PUSH_POP no longer available.
