From 35485da996c21efc9a574520a737e10fcbeab654 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: New. * docs/_build/texinfo/Makefile: New. * docs/_build/texinfo/factorial.png: New. * docs/_build/texinfo/libgccjit.texi: New. * docs/_build/texinfo/sum-of-squares.png: New. * docs/conf.py: New. * docs/examples/tut01-hello-world.c: New. * docs/examples/tut02-square.c: New. * docs/examples/tut03-sum-of-squares.c: New. * docs/examples/tut04-toyvm/Makefile: New. * docs/examples/tut04-toyvm/factorial.toy: New. * docs/examples/tut04-toyvm/fibonacci.toy: New. * docs/examples/tut04-toyvm/toyvm.c: New. * docs/index.rst: New. * docs/internals/index.rst: New. * docs/intro/factorial.png: New. * docs/intro/index.rst: New. * docs/intro/sum-of-squares.png: New. * docs/intro/tutorial01.rst: New. * docs/intro/tutorial02.rst: New. * docs/intro/tutorial03.rst: New. * docs/intro/tutorial04.rst: New. * docs/topics/contexts.rst: New. * docs/topics/expressions.rst: New. * docs/topics/functions.rst: New. * docs/topics/index.rst: New. * docs/topics/locations.rst: New. * docs/topics/objects.rst: New. * docs/topics/results.rst: New. * docs/topics/types.rst: New. * dummy-frontend.c: New. * jit-builtins.c: New. * jit-builtins.h: New. * jit-common.h: New. * jit-playback.c: New. * jit-playback.h: New. * jit-recording.c: New. * jit-recording.h: New. * libgccjit++.h: New. * libgccjit.c: New. * libgccjit.h: New. * libgccjit.map: New. * notes.txt: New. gcc/testsuite/ChangeLog: * ChangeLog.jit: New. * jit.dg/all-non-failing-tests.h: New. * jit.dg/harness.h: New. * jit.dg/jit.exp: New. * jit.dg/test-accessing-struct.c: New. * jit.dg/test-accessing-union.c: New. * jit.dg/test-array-as-pointer.c: New. * jit.dg/test-arrays.c: New. * jit.dg/test-calling-external-function.c: New. * jit.dg/test-calling-function-ptr.c: New. * jit.dg/test-combination.c: New. * jit.dg/test-dot-product.c: New. * jit.dg/test-empty.c: New. * jit.dg/test-error-accessing-field-in-other-struct.c: New. * jit.dg/test-error-adding-to-terminated-block.c: New. * jit.dg/test-error-array-as-pointer.c: New. * jit.dg/test-error-bad-cast.c: New. * jit.dg/test-error-block-in-wrong-function.c: New. * jit.dg/test-error-call-through-ptr-with-mismatching-args.c: New. * jit.dg/test-error-call-through-ptr-with-non-function.c: New. * jit.dg/test-error-call-through-ptr-with-non-pointer.c: New. * jit.dg/test-error-call-through-ptr-with-not-enough-args.c: New. * jit.dg/test-error-call-through-ptr-with-too-many-args.c: New. * jit.dg/test-error-call-with-mismatching-args.c: New. * jit.dg/test-error-call-with-not-enough-args.c: New. * jit.dg/test-error-call-with-too-many-args.c: New. * jit.dg/test-error-dereference-field-of-non-pointer.c: New. * jit.dg/test-error-dereference-read-of-non-pointer.c: New. * jit.dg/test-error-get-type-bad-enum.c: New. * jit.dg/test-error-index-not-a-numeric-type.c: New. * jit.dg/test-error-mismatching-types-in-assignment.c: New. * jit.dg/test-error-mismatching-types-in-call.c: New. * jit.dg/test-error-missing-return.c: New. * jit.dg/test-error-new-binary-op-bad-op.c: New. * jit.dg/test-error-new-function-bad-kind.c: New. * jit.dg/test-error-new-unary-op-bad-op.c: New. * jit.dg/test-error-null-passed-to-api.c: New. * jit.dg/test-error-return-within-void-function.c: New. * jit.dg/test-error-unreachable-block.c: New. * jit.dg/test-error-unterminated-block.c: New. * jit.dg/test-error-value-not-a-numeric-type.c: New. * jit.dg/test-expressions.c: New. * jit.dg/test-factorial.c: New. * jit.dg/test-fibonacci.c: New. * jit.dg/test-functions.c: New. * jit.dg/test-fuzzer.c: New. * jit.dg/test-hello-world.c: New. * jit.dg/test-linked-list.c: New. * jit.dg/test-long-names.c: New. * jit.dg/test-nested-contexts.c: New. * jit.dg/test-nested-loops.c: New. * jit.dg/test-operator-overloading.cc: New. * jit.dg/test-quadratic.c: New. * jit.dg/test-quadratic.cc: New. * jit.dg/test-reading-struct.c: New. * jit.dg/test-string-literal.c: New. * jit.dg/test-sum-of-squares.c: New. * jit.dg/test-threads.c: New. * jit.dg/test-types.c: New. * jit.dg/test-using-global.c: New. * jit.dg/test-volatile.c: New. include/ChangeLog: * ChangeLog.jit: New. libbacktrace/ChangeLog: * ChangeLog.jit: New. libcpp/ChangeLog: * ChangeLog.jit: New. libdecnumber/ChangeLog: * ChangeLog.jit: New. libiberty/ChangeLog: * ChangeLog.jit: New. zlib/ChangeLog: * ChangeLog.jit: New.
