Alkis Evlogimenos 5a92240270 Use newly added next() and prior() utility functions. 
llvm-svn: 11430
 2004-02-14 01:18:34 +00:00
Alkis Evlogimenos 7c6e4d5ae6 Add next() and prior() iterator utility functions. Unlike std::advance 
they do not modify the passed iterator but return a copy.

next(myIt) returns copy of myIt incremented once
next(myIt, n) returns copy of myIt incremented n times
prior(myIt) returns copy of myIt decremented once
prior(myIt, n) returns copy of myIt decremented n times

While at it remove obsolete implementation of mapped_iterator.

llvm-svn: 11428
 2004-02-14 01:07:17 +00:00
Alkis Evlogimenos ddcb4ad53e Use std::numeric_limits<float>::infinity() instead of 
std::numeric_limits<float>::max() for weighting preallocated
intervals.

Chris Lattner 0997f207c2 Use intrinsic lowering like the rest of the backends. Get rid of crufty hacky 
code that worked around problems in the mangler

llvm-svn: 11425
 2004-02-14 00:30:31 +00:00
Chris Lattner 77687a9746 Fix the logic in the name mangler. If there are two symbols named 'X', and one 
is external, make sure to mangle the *internal* one, not external one

Chris Lattner 7b5f374a18 There is no need to emit a shift if the size is constant, which is common

Chris Lattner c5a4641c21 Do not advertise our -c option anymore 
llvm-svn: 11413
 2004-02-13 23:24:46 +00:00
Chris Lattner 92849b7dc9 Mercilessly rip the cbackend out of llvm-dis. Leave a helpful error message 
for those who have not heard the news.

Chris Lattner c7dd48567f The cbackend has never had anything to do with llvm assembly writing 
llvm-svn: 11411
 2004-02-13 23:19:51 +00:00
Chris Lattner 3fba9dc096 Add support for -march=c 
llvm-svn: 11410
 2004-02-13 23:19:09 +00:00
Chris Lattner 0591bb5bc8 Convert the C backend into a target, for use with LLC. This allows us to use 
the lowerallocations pass to eliminate malloc/free warnings and hackish code

llvm-svn: 11409
 2004-02-13 23:18:48 +00:00
Chris Lattner 9fae109121 Change how we create the cwriter, and add a buttload of libraries that it now 
needs.  This will be fixed shortly

llvm-svn: 11407
 2004-02-13 23:01:14 +00:00
Chris Lattner b09176a1e2 Change access to the cwriter 
llvm-svn: 11406
 2004-02-13 23:00:45 +00:00
Chris Lattner d2b6e183e9 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

llvm-svn: 11405
 2004-02-13 23:00:29 +00:00
Chris Lattner 067b6bb9b2 New testcase. The CFE should not generate illegal LLVM intrinsics, even if 
the input program is horribly broken (like 126.gcc).

llvm-svn: 11401
 2004-02-13 22:04:41 +00:00
John Criswell 3b4195f344 Added check for target machine endian-ness and put the result into 
Makefile.config (ENDIAN variable is set to big or little).

Chris Lattner d17e15eddd Add support for a bunch more functions 
llvm-svn: 11395
 2004-02-13 21:21:48 +00:00
Alkis Evlogimenos 8cdd0215bf Remove getAllocatedRegNum(). Use getReg() instead. 
llvm-svn: 11393
 2004-02-13 21:01:20 +00:00
Alkis Evlogimenos ef9d025ebe Mark MachineBasicBlock::operator[] deprecated. 
llvm-svn: 11392
 2004-02-13 20:05:56 +00:00
Alkis Evlogimenos 1aa50dfae5 Define DEPRECATED so that it can be used in function and variable 
declarations.

llvm-svn: 11391
 2004-02-13 20:05:44 +00:00
Chris Lattner e00227248e Add support for fopen/fclose. Specifically with fopen, we were marking all of the 
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

Alkis Evlogimenos de6a381691 Use getNumVirtualRegs().

Chris Lattner 963f273734 Bug fixed 
llvm-svn: 11385
 2004-02-13 17:03:01 +00:00
Chris Lattner 283ffdfac5 Fix compilation of 126.gcc: intrinsic functions cannot throw, so they are not 
allowed in invoke instructions.  Thus, if we are inlining a call to an intrinsic
function into an invoke site, we don't need to turn the call into an invoke!

John Criswell d6687b9b82 Updated to list all code/directories that have additional or alternate 
licensing information.

Also added note to indicate that warrany disclaimer and the no-endorsement
clause applies to everything.
