I'd like to merge my "dmalcolm/jit" branch into trunk and I wanted to
start a discussion here about what that would take (and maybe get some
code reviewed).
Attached is a (compressed) diff of the branch against trunk (as of
r215090 on 2014-09-09, so a little out-of-date).
As mentioned before, I'm using Sphinx for documentation (and also
checking in autogenerated .texinfo for those who want docs without a
sphinx toolchain installed).
Prebuilt HTML documentation (via Sphinx) can be seen at:
https://dmalcolm.fedorapeople.org/gcc/libgccjit-api-docs/index.html
The API docs currently have this caveat:
"Note that libgccjit is currently of "Alpha" quality; the APIs
are not yet set in stone, and they shouldnât be used in
production yet."
Do I need to declare a frozen API before this can go in, or is it
acceptable to carry this within the tree as an "experimental" feature?
Bootstrapped®rtested on x86_64-unknown-linux-gnu (Fedora 20). No
differences found in 16 common .sum files, relative to a control build
of r215090. (adding --enable-host-shared when building with "jit" in
the set of enabled languages).
For some reason "make check" isn't yet running the jit testsuite, and
"make check-jit" doesn't yet work.
That said, "make check-parallel-jit" does work, with the new jit.sum
containing:
=== jit Summary ===
# of expected passes 4301
The attached diff contains ChangeLog.jit entries per-directory (some of
which contain changes that have already been merged, which leads to some
directories that gain a ChangeLog.jit but no other change).
Here's an overall ChangeLog relating to the proposed merger:
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.
* ipa-reference.c (ipa_init): Move static bool init_p from here
to...
(ipa_init_p): New file-scope variable, so that it can be reset
when repeatedly invoking the compiler within one process by...
(ipa_reference_c_finalize): New function.
* ipa-reference.h (ipa_reference_c_finalize): New.
* ipa.c (ipa_c_finalize): New.
* main.c (main): Replace invocation of toplev_main with
construction of a toplev instance, and call its "main" method.
* params.c (global_init_params): Add an assert that params_finished is
false.
(params_c_finalize): New.
* params.h (params_c_finalize): New.
* passes.c (execute_ipa_summary_passes): Set "current_pass" before
invoking generate_summary.
(ipa_write_summaries_2): Assign "pass" to "current_pass" global
before calling write_summary hook.
(ipa_write_optimization_summaries_1): Likewise when calling
write_optimization_summary hook.
(ipa_read_summaries_1): Likewise for read_summary hook.
(ipa_read_optimization_summaries_1): Likewise for
read_optimization_summary hook.
* predict.c (predict_c_finalize): New.
* stringpool.c (init_stringpool): Clean up if we're called more
than once.

* toplev.c: Include "dwarf2out.h", "ipa-reference.h", "gcse.h".
(general_init): Reset "input_location" to UNKNOWN_LOCATION.
(initialize_rtl): Move static local "initialized_once"
into file scope, and rename to...
(rtl_initialized): New variable.
(do_compile): Remove argument. Move timevar initialization from
here to toplev::start_timevars.
(toplev::toplev, toplev::~toplev, toplev::start_timevars,
toplev::finalize): New functions.
(toplev_main): Rename to...
(toplev::main): ...this.
