Chris Lattner 4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

Also, fix some undefined behavior, expecting | on booleans to evaluate
left-to-right.

Reid Spencer 45101043ef Put in a #error in the event that we don't have an mmap that can map a file 
into memor. This is just a reminder that the ReadFileIntoAddressSpace
function needs to be properly converted to lib/System and implemented via
read/write if there's no mmap of file support.

Reid Spencer ac16ea98de Fix problems with AC_FUNC_MMAP_FILE and AC_LINK_USE_R that caused problems 
with correctly recognizing mmap of files and the linker's support of -r.

Reid Spencer a9317d68b6 The problem with depending on the internal implementation of third party 
tools is that you break when they change. This is a case in point.

Reid Spencer f184a86f05 Adjust the libtool macros so that libtool's name is "mklib". Also, tidy up 
the use of obsolete macros, hopefully making us more compliant on more sys.

 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.

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 :(

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.

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
