Chris Lattner 5174f436d2 Ugh, the upgrade of zion brought in GCC 3.3.2, our arch nemesis.

Chris Lattner aa5b25eae6 Run DSE at link-time, and turn on an IP alias analysis by default in gccld!
The -disable-globalsmodref is temporary and will be removed eventually.

Chris Lattner b696462260 Fix conservative assumption, which was quite broken. Also, notice that
functions known to not access memory (like sin/cos) don't access memory! :)

Chris Lattner 3a353e84b7 Complete rewrite of this pass to be faster, use less memory, be easier to
understand, and more accurate to boot!  This implements
GlobalModRef/purecse.ll over the previous impl.

Chris Lattner 9b323c3521 Use context-sensitive alias analysis to avoid pessimization in clients of
AliasSetTracker (dse and licm).  This implements
DeadStoreElimination/context-sensitive.llx

Chris Lattner 0ff7eb9ba9 New testcase for list slicing
llvm-svn: 15248
2004-07-27 01:00:56 +00:00
Chris Lattner 8bf9e06ddd Add initial support for list slices. This currently allows you to do stuff
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.

Reid Spencer a559cb8e10 A utility to run an arbitrary program on each of the LLVM source files.
This is like llvmgrep but instead of running grep, it runs the command
given by the first argument. For example, to find the top ten files with
the most lines in llvm, you could:

utils/llvmdo wc -l | sort -nb | tail

Or, to find any source files with the wrong permissions, you could:

utils/llvmdo ls -l | grep -v rw-r--r--

Hopefully, you get the idea.

Misha Brukman b5ed14486b Do not store the stack pointer if the stack size is 0.
Also, convert C-style comments to C++ and make sure code wraps at 80 cols.

Misha Brukman 58499ead7d ADDI can take several forms, including:
addi r1, r2, 0
  addi r1, <frame index #n>, 0

so we must check for the second parameter being a register for this instruction
to be considered a reg-to-reg copy.

Misha Brukman bca562404c Renamed files to have the `X86' prefix for uniqueness purposes.
All CVS history was renamed, the *,v were copied over.  No worries.

Chris Lattner c2cb34ae61 Fix an extremely serious regression that was causing LLVM basic blocks to be
scrambled around almost at random, having really bad effects on icache locality.

2004-07-26 01:22:59 +00:00
Chris Lattner 74635dc879 Fix a serious bug in the double constant reader. In particular, because
(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

llvm-svn: 15224
2004-07-25 23:15:44 +00:00
Chris Lattner 21a015c12f Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the
glibc 'nan' function because the initializer is not a string.  This breaks when used in a global
initializer.  Try compiling this testcase for example:

%X = global float <some nan value>
