Chris Lattner d72c3eb54e Change the ExitBlocks list from being explicitly contained in the Loop
structure to being dynamically computed on demand.  This makes updating
loop information MUCH easier.

execute other CallGraphSCCPasses after the inliner without crashing.

Chris Lattner 4d25c86b52 Remove the "really gross hacks" that are there to deal with recursive functions.
Now we collect all of the call sites we are interested in inlining, then inline
them.  This entirely avoids issues with trying to inline a call site we got by
inlining another call site.  This also eliminates iterator invalidation issues.

Chris Lattner 2dc85b27e4 This change makes two big adjustments.
* Be a lot more accurate about what the effects will be when inlining a call
   to a function when an argument is an alloca.
 * Dramatically reduce the penalty for inlining a call in a large function.
   This heuristic made it almost impossible to inline a function into a large
   function, no matter how small the callee is.

Chris Lattner fe6f2e3e80 Implement ArgumentPromotion/aggregate-promote.ll
This allows pointers to aggregate objects, whose elements are only read, to
be promoted and passed in by element instead of by reference.  This can
enable a LOT of subsequent optimizations in the caller function.

It's worth pointing out that this stuff happens a LOT of C++ programs, because
objects in templates are generally passed around by reference.  When these
templates are instantiated on small aggregate or scalar types, however, it is
more efficient to pass them in by value than by reference.

This transformation triggers most on C++ codes (e.g. 334 times on eon), but
does happen on C codes as well.  For example, on mesa it triggers 72 times,
and on gcc it triggers 35 times.  this is amazingly good considering that
we are using 'basicaa' so far.

Chris Lattner 8d1da1abee My faith in programmers has been found to be totally misplaced. One would
assume that if they don't intend to write to a global variable, that they
would mark it as constant.  However, there are people that don't understand
that the compiler can do nice things for them if they give it the information
it needs.

This pass looks for blatently obvious globals that are only ever read from.
Though it uses a trivially simple "alias analysis" of sorts, it is still able
to do amazing things to important benchmarks.  253.perlbmk, for example,
contains several ***GIANT*** function pointer tables that are not marked
constant and should be.  Marking them constant allows the optimizer to turn
a whole bunch of indirect calls into direct calls.  Note that only a link-time
optimizer can do this transformation, but perlbmk does have several strings
and other minor globals that can be marked constant by this pass when run
from GCCAS.

176.gcc has a ton of strings and large tables that are marked constant, both
at compile time (38 of them) and at link time (48 more).  Other benchmarks
give similar results, though it seems like big ones have disproportionally
more than small ones.

This pass is extremely quick and does good things.  I'm going to enable it
in gccas & gccld.  Not bad for 50 SLOC.

Chris Lattner 6dc0ae2d18 Speed up the predicate used to decide when to inline by caching the size
of callees between executions.

On eon, in release mode, this changes the inliner from taking 11.5712s
to taking 2.2066s.  In debug mode, it went from taking 14.4148s to
taking 7.0745s.  In release mode, this is a 24.7% speedup of gccas, in
debug mode, it's a total speedup of 11.7%.

This also makes it slightly more aggressive.  This could be because we
are not judging the size of the functions quite as accurately as before.
When we start looking at the performance of the generated code, this can
be investigated further.

Chris Lattner ec6d7a6df3 This is effectively a complete rewrite of the globaldce algorithm, resulting
in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

Chris Lattner ffc2d16f21 Final cleanup: remove dead code
llvm-svn: 8291
2003-09-01 18:01:36 +00:00
Chris Lattner 267f20475b Not only is this a lot smaller, it actually works if there is already a
function with the right name in the module.

Chris Lattner d4a1af7d49 If "These should be used only by the auto-parallelization pass", we might as
well put them INTO the auto-par pass.

Chris Lattner 685dc1ea98 Moved all of the cilkifier stuff into lib/Transforms/IPO, as it really is not
support stuff.

Chris Lattner 6c6ba71cea Minor cleanups
Do not #include Parallelize.h, it's just a subset of Cilkifier.h

2003-09-01 16:42:16 +00:00
Chris Lattner 8ef1b88aef Change the RaiseAllocations pass to be a Pass instead of a BasicBlock pass.
This makes it more efficient: it doesn't have to scan the whole program, so
it performs work proportional to the number of malloc/free calls in the
program, not the size of the program.

Chris Lattner d075cc282b Heavily refactor code:
* Separate the policy decisions into a derived class [InlineSimple]
  * Move the inlining mechanics into a base class [Inliner]
  * Change the inliner to be an SCCPass, making it more structured and
    eventually pipelinable with other SCC passes

John Criswell 449670a8f7 Fixed a segfault in gccld.
The original code does not work because the value from WorkList.end() is
invalidated once WorkList.erase() is called.  To ensure proper functionality,
we must ensure that WorkList.erase() is always called before WorkList.end().

Chris Lattner fd5d323ea9 When internalizing global ctor/dtor list, also mark it constant. This is gross, but
