Reid Spencer 200dcd9e68 Numerous fixes to convert ~ into ; that (probably) occurred during data 
transmission.

Chris Lattner 85927a6730 The lexicon doc is more of a user guide than programming dox

Reid Spencer eb61eb2e32 Make the "Warning" notice a LOT more prominent. 
llvm-svn: 16414
 2004-09-19 22:30:53 +00:00
Reid Spencer 2aeccd0f1c Add in version dependency checks on all the tools we depend on. This is 
necessary to ensure that a consistent configuration is created on each
platform. Certain definitions we use (like m4/libtool.m4) require certain
versions of the tools and we can no longer be slack about this or we'll
have problems with mis-configured builds.

llvm-svn: 16412
 2004-09-19 22:14:24 +00:00
Reid Spencer dc6f5680f3 Add our own version of libtool.m4 instead of relying on the installed one. 
This is a potential version mismatch problem because this file came from
libtool 1.5.10. If you're running a different version of libtool, the
checks in this file may not be quite right. Having our own version of this
file violates the spirit of libtool and is only provided to change the name
of "libtool" to "mklib". This is done so that the name "libtool" does not
conflict with the "lib" directory when doing tab completion and your
$objdir == $srcdir.

llvm-svn: 16408
 2004-09-19 19:17:10 +00:00
Chris Lattner d6d99dfa3f Fix a nasty iterator invalidation problem I introduced yesterday. This 
unfortunately is the cause of a bunch of failures from tonight, and the
reason the tester is running so slow :(

llvm-svn: 16407
 2004-09-19 19:01:06 +00:00
Chris Lattner 855a4ff4dd Remove a whole bunch of horrible hacky code that was used to promote allocas 
whose addresses where used by trivial phi nodes and select instructions.  This
is now performed by the instcombine pass, which is more powerful, is much
simpler, and is faster.  This allows the deletion of a bunch of code, two
FIXME's and two gotos.

llvm-svn: 16406
 2004-09-19 18:51:51 +00:00

Chris Lattner 6455c51ab6 Fix the inliner to always delete any edges from the external call node to 
a function being deleted.  Due to optimizations done while inlining, there
can be edges from the external call node to a function node that were not
apparent any longer.

This fixes the compiler crash while compiling 175.vpr

Reid Spencer f27c4cde06 Okay, the list of link-time passes wasn't such a hot idea. Its prone to

Alkis Evlogimenos fae8f6a4fb Be a bit more efficient when processing the active and inactive
