Reid Spencer 713eedc1fb For PR797: 
Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.

Alkis Evlogimenos 9ead0d7b4c Rename createPromoteMemoryToRegister() to 
createPromoteMemoryToRegisterPass() to be consistent with other pass
creation functions.

Chris Lattner a9beaacac6 move the reassociation pass after the LICM pass. This speeds up mgrid 
from 10.27s to 9.57s with the CBE.

Reid Spencer 996ec72d48 For PR351: 
* Place a try/catch block around the entire tool to Make sure std::string
  exceptions are caught and printed before exiting the tool.
* Make sure we catch unhandled exceptions at the top level so that we don't
  abort with a useless message but indicate than an unhandled exception was
  generated.

Reid Spencer e2b14e52c7 Support the gas option --traditional-format which, for some reason, gets 
passed to gccas when the --program-prefix option is used to configure CFE.

bytecode can be defeated.

Reid Spencer 7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Chris Lattner 7ba1be09b3 Remove redundant SCCP pass 
Add new DSE pass.  Add a temporary option to disable it in case we need it
This is going in after the July 22 nightly tester run, so we'll wait until the 23rd to see it
:)

Chris Lattner 024385ba5f Turn on argument promotion in gccas. This can give us substantially better 
code in cases where the file has lots of static functions or anon namespaces.

the tool.

Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas. 
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

Chris Lattner 298d2f090f Make sure to verify the result before writing out the bytecode file. Not doing 
so can cause obscure errors downstream.

Chris Lattner cf1755a6f3 Add a -disable-opt flag to gccas, so that we can use -Wa,-disable-opt just 
like -Wl,-disable-opt

Chris Lattner db8a179838 Revert the previous patch since it causes lots of miscompilations. :( :(

 2003-11-22 19:07:47 +00:00
Chris Lattner 52b4fb3fde Reorder passes a bit. In particular, it makes sense to run globaldce IMMEDIATELY after funcresolve. Also, run the mem2reg pass _early_ so that IPCP and DAE actually do stuff. 
Run instcombine and simplify cfg after this to cleanup the intraprocedural messes we create.

Chris Lattner 3334c884bc Give this file a proper header 
llvm-svn: 9141
 2003-10-15 21:49:57 +00:00
Chris Lattner 4973805acd The levelraise pass is a broken old piece of crufty code that should be 
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.
