Owen Anderson 4c54024319 Make the copy constructor of SmallPtrSet much faster.

Anton Korobeynikov 0c46451d2b Heal EH handling stuff by emitting correct offsets to callee-saved registers. 
Pretty hackish, but code itself is dirty mess, so we won't make anything worse. :)

load elimination code from RedundantLoadElimination.

Chris Lattner 1af0e0116a avoid std::string yet again.

 2007-07-24 06:59:01 +00:00
Chris Lattner 4c4a245475 Use a smallstring instead of an std::string in FileChanged to avoid some malloc traffic. 
This speeds up -E on xalancbmk by 2.4%

Chris Lattner 830a77fd65 check in an experiment that didn't work out, to allow for future investigation.

Chris Lattner 8996ffffe5 Add a cache to SourceManager to accellerate line # lookup. This is a 
bottleneck for -E computation, because every token that starts a line needs
to determine *which* line it is on (so -E mode can insert the appropriate 
vertical whitespace).  This optimization improves this common case where
it is striding through the line # table.

This speeds up -E on xalancbmk by 3.2%

2. Fold an if statement into the Assert1 macro call.

Chris Lattner d63c8a5963 Fix two paste-avoidance bugs I introduced last night. Patch 
by Neil Booth.  This fixes Preprocessor/output_paste_avoid.c

llvm-svn: 40454
 2007-07-23 23:21:34 +00:00
Reid Spencer 6c2b393f0c Add better verification of attributes on function types. It is not permitted 
to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.

Duncan Sands b063fa59d3 The Ada f-e produces various auxiliary output files 
that cannot be suppressed and cannot be redirected:
they are dumped in the current working directory.
When running the testsuite this means that these
files do not end up in the Output directory.  The
best solution I could find is to change directory
into Output before running tests.

Duncan Sands 1747440364 For multipart tests, place the parts with no 
RUN line in Support.  Give up on sending output
to /dev/null - this cannot always be arranged.

Chris Lattner 0af9823e4d Avoid calling getSpelling at all for identifiers, which are 
trivial to handle and very very common.  This speeds up -E on 
447.dealII by 2.5%

Chris Lattner 4418ce1091 change the concatenation avoidance algorithm to be partially table-driven 
and avoid computing the spelling of tokens when not needed.  This speeds
up -E on 447.dealII by 2.2%

llvm-svn: 40421
 2007-07-23 06:09:34 +00:00
Chris Lattner e4c566c604 If a token doesn't need cleaning, we can get its first character 
without having to get the whole token.  This speeds up -E on 
447.dealII by 1.8%

 2007-07-23 05:18:42 +00:00

Chris Lattner 43eafb4ed5 implement a missing feature in the #include handler, where 
it did not handle <xyz> headers coming from macro expansions.
This requires special treatment, as the include name is lexed
as multiple tokens, which require reassembly before processing.
