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.
