5ecdf1a70a Eliminate comparisons between GC allocations and constants. This removes some
`assert(this !is null)`s when member functions get inlined.

Also tweak pass order a bit.

465f15eda0 Return void* from _d_allocclass so LLVM doesn't do weird things with it...
This allows `-instcombine` followed by `-gvn` to do devirtualization, so add
`-gvn` in strategic places in the default pass order.

bc7737a03b Add some passes that opt runs to the default pass list. 2009-06-11 16:57:45 +02:00

b999f679a7 Teach -dgc2stack to promote GC allocations in simple loops to stack
allocations too. (A "simple" loop is one where the allocation isn't used in a
subsequent iteration)

This also means it's no longer necessary to run this pass multiple times.
Running it once after inlining should now catch all cases.

96650855ed Add a pass to strip the bodies of available_externally functions so string
literals and `TypeInfo`s only referenced by them can be deleted by `-globaldce`.

96fdcd6347 Run semantic3 on imported modules, and emit new symbols with
`available_externally` linkage. This allows the inliner to inline functions from
other modules while telling the code generator to ignore those functions (treat
them as declarations)
Still generates a few extra `TypeInfo`s and strings...
Disabled when generating debug info because I don't really understand it, and it
doesn't like this.

be more useful.

6619190ba5 * Add -functionattrs to default pass list so -dgc2stack is more effective
when callees aren't inlined. This should also improve various standard LLVM
  optimizations.
* Comment out some verbose logging.

865ae79e27 Strip metadata even when addPassesForOptLevel() isn't called, for instance when
only inlining or when manually specifying passes.

87d960c29a Fix build when USE_METADATA is off. 2009-05-02 19:03:33 +03:00

262ef97945 There's an issue with LLVM metadata support; it triggers an assert when trying
to generate asm for code with metadata globals.
This new pass is used as a workaround: it strips metadata from the module before
it reaches the code generator.
Obviously, this is disabled if LLVM doesn't support metadata.

cff0f1f446 Implement another D-specific pass: -dgc2stack
This one promotes GC allocations to stack memory when it can determine it's safe
to do so.
Not all GC calls are recognized yet (in fact only one *is* recognized for now).
Needs metadata, so disabled for LLVM versions that don't support it.

da4450d2f5 Make sure this still compiles after LLVM r70437, which introduces a
specialization for command-line option template parser<char> which does the
wrong thing for us...

0df1e34eb2 Implement first D-specific optimization pass: -simplify-drtcalls.
It uses the machinery of the standard -simplify-libcalls pass, but optimizes
calls to the D runtime instead of calls to C libraries.

At the moment, these optimizations are implemented by this pass:
 - Avoid the runtime call for `arr.length = newlen` if it can determine that
   the new length isn't longer than the old one.
 - Ditto for `cast(T[]) arr` if it will clearly always succeed.
   (e.g. if the length of the original array is zero, or if the old element
   size is a multiple of the new element size)

5ea141e919 Tweak some optimizations.
Delegates passed to inlined functions now also stand a chance of being inlined.
This should make opApply as efficient as a regular loop, as long as both opApply
and the foreachbody are eligible for inlining; which is to say most non-virtual
opApply invocations will likely get fully inlined now.
(Note: above requires -O2 -enable-inlining or -O3)

257d305032 Change meaning of optimization levels: -O0 now means 'no optimization' like with
other compilers.

e129494812 Allow specific optimization passes to be requested from the command line.
Now you can run "`ldc test.d -c -mem2reg -simplifycfg`" if you feel the urge.
The -O<N> options are still supported, and are inserted in the passes list in
the position where they appear on the command line.
(so -simplifycfg -O1 -instcombine does the "right thing")

One small change: -inline is renamed to -enable-inlining due to a naming
conflict with the option to add the -inline pass. -inline now inserts the
inlining pass in the position specified, not in the middle of -O<N>.
(ldmd has been updated to translate -inline to -enable-inlining)

6c5c7ee1c1 Fixed the optimizer thing, since llvm PR 2800 is already fixed, users need to upgrade LLVM to latest svn. 2008-09-18 21:07:35 +02:00

1daa67ba50 Removed useless assert in ArrayLiteralExp::toConstElem
Added second verification pass after optimization
Commented an optimization pass out from lvl2, it turns the IR invalid, see llvm PR 2800

928f7d4de5 [svn r296] Removed: the 'suite' dir, it never took off!
Fixed: foreach statement, key-type checks were buggy.
Fixed: setting LLVMDC versions on the command line is now an error.
Fixed: array compare runtime had incorrect param attrs on call.
Fixed: index expressions on dynamic array slices w/o storage was broken.
Fixed: scope classes had incorrect finalization in some cases.
Fixed: when outputting !ClassInfoS !OffsetTypeInfoS, static class members were trying to be included, crashing the compiler.
Fixed: calling LLVMDC with -inline but not any -O option caused assertion failure.
Changed: the runtime now uses a single interface to "get" to !TypeInfoS, part of eliminating duplicate !TypeInfo codegen.

bc08c6fcb1 [svn r135] * Merged DMD 1.025 *
* Fixed a minor linking order mishap *
* Added an command line option -annotate *
* Fixed some problems with running optimizations *
* Added std.stdio and dependencies to lphobos (still not 100% working, but compiles and links) *
* Fixed problems with passing aggregate types to variadic functions *
* Added initial code towards full GC support, currently based on malloc and friends, not all the runtime calls the GC yet for memory *
* Fixed problems with resolving nested function context pointers for some heavily nested cases *
* Redid function argument passing + other minor code cleanups, still lots to do on this end... *
