Eli Friedman 36b9026fa7 PR4123: don't crash when inlining a call which uses its own result.

Devang Patel 046bf624b9 While inlining, clone llvm.dbg.func.start intrinsic and adjust
llvm.dbg.region.end instrinsic. This nested llvm.dbg.func.start/llvm.dbg.region.end pair now enables DW_TAG_inlined_subroutine support in code generator.

Chris Lattner 184f1be4a8 Add a new "available_externally" linkage type. This is intended
to support C99 inline, GNU extern inline, etc.  Related bugzilla's
include PR3517, PR3100, & PR2933.  Nothing uses this yet, but it
appears to work.

Evan Cheng 1c94228de3 If a function is marked alwaysinline, it must be inlined (possibly for correctness). Do so even if the callee has dynamic alloca and the caller doesn't.

Chris Lattner feb129e813 Fix a nasty bug (PR3550) where the inline pass could incorrectly mark
calls with the tail marker when inlining them through an invoke.  Patch,
testcase, and perfect analysis by Jay Foad!

Dale Johannesen 433a9086c0 Enable recursive inlining. Reduce inlining threshold
back to 200; 400 seems to be too high, loses more than
it gains.

Dale Johannesen b48fc71fc6 Do not inline functions with (dynamic) alloca into
functions that don't already have a (dynamic) alloca.
Dynamic allocas cause inefficient codegen and we shouldn't
propagate this (behavior follows gcc).  Two existing tests
assumed such inlining would be done; they are hacked by
adding an alloca in the caller, preserving the point of
the tests.

Daniel Dunbar 3933e66a89 Add InlineCost class for represent the estimated cost of inlining a
function.
 - This explicitly models the costs for functions which should
   "always" or "never" be inlined. This fixes bugs where such costs
   were not previously respected.

Matthijs Kooijman 0620096c18 Move two tests from SRETPromotion to Inline, since they only call opt -inline.
llvm-svn: 54465
2008-08-07 15:36:46 +00:00
Matthijs Kooijman d1057f49b4 Let some more tests ignore expected output on stderr.
Also, use > %t instead of -o %t for output in one test since that also works
when %t already exists.

This fixes 6 testcases.

Duncan Sands 053c9871cd Revert r46393: readonly/readnone functions are no
longer allowed to write through byval arguments.

llvm-svn: 46416
2008-01-27 18:12:58 +00:00
Duncan Sands dc157a4f0a Invert this test, because it is wrong if we allow
readonly functions to use byval parameters as local
storage (how much do we want this?).

llvm-svn: 46399
2008-01-26 12:33:01 +00:00
Chris Lattner 4f6c81ac68 we don't have to make an explicit copy of a byval argument when
inlining a function if we know that the function does not write
to *any* memory.  This implements test/Transforms/Inline/byval2.ll

Duncan Sands aa31b92508 When inlining through an 'nounwind' call, mark inlined
calls 'nounwind'.  It is important for correct C++
exception handling that nounwind markings do not get
lost, so this transformation is actually needed for
correctness.

Duncan Sands b5a79d0eaa Make invokes of inline asm legal. Teach codegen
how to lower them (with no attempt made to be
efficient, since they should only occur for
unoptimized code).

llvm-svn: 45108
2007-12-17 18:08:19 +00:00
Duncan Sands 8e4847ee95 Make instcombine promote inline asm calls to 'nounwind'
calls.  Remove special casing of inline asm from the
inliner.  There is a potential problem: the verifier
rejects invokes of inline asm (not sure why).  If an
asm call is not marked "nounwind" in some .ll, and
instcombine is not run, but the inliner is run, then
an illegal module will be created.  This is bad but
I'm not sure what the best approach is.  I'm tempted
to remove the check in the verifier...

Reid Spencer d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the
global variables that needed to be passed in. This makes it possible to
