From 6c249ec2c5ab49d1ecd93c17019e8f95c1df6f01 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Tue, 11 Nov 2014 21:55:52 +0000 Subject: Merger of dmalcolm/jit branch from git ChangeLog: * ChangeLog.jit: New. * MAINTAINERS (Various Maintainers): Add myself as jit maintainer. contrib/ChangeLog: * ChangeLog.jit: New. * jit-coverage-report.py: New file: a script to print crude code-coverage information for the libgccjit API. gcc/ChangeLog: * ChangeLog.jit: New. * Makefile.in (doc_build_sys): New variable, set to "sphinx" if sphinx is installed, falling back to "texinfo" otherwise. (FULL_DRIVER_NAME): New variable, adapted from the install-driver target. New target, a symlink within the builddir, linked to "xgcc", for use when running the JIT library from the builddir. (MOSTLYCLEANFILES): Add FULL_DRIVER_NAME. (install-driver): Use $(FULL_DRIVER_NAME) rather than spelling it out. * configure.ac (doc_build_sys): New variable, set to "sphinx" if sphinx is installed, falling back to "texinfo" otherwise. (GCC_DRIVER_NAME): Generate a gcc-driver-name.h file containing GCC_DRIVER_NAME for the benefit of jit/internal-api.c. * configure: Regenerate. * doc/install.texi (--enable-host-shared): Specify that this is required when building libgccjit. (Tools/packages necessary for modifying GCC): Add Sphinx. * timevar.def (TV_JIT_REPLAY): New. (TV_ASSEMBLE): New. (TV_LINK): New. (TV_LOAD): New. gcc/java/ChangeLog: * gcc/ChangeLog.jit: New. gcc/jit/ChangeLog: * ChangeLog.jit: New. * ChangeLog: New. * Make-lang.in: New. * TODO.rst: New. * config-lang.in: New. * docs/Makefile:
