for those who have not heard the news.

d076de4bf3 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

93da3b1886 Change how we create the cwriter, and add a buttload of libraries that it now 
needs.  This will be fixed shortly

d2cd0afd11 Change access to the cwriter 
llvm-svn: 11406
 2004-02-13 23:00:45 +00:00

81155b0069 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

110d7bd802 New testcase. The CFE should not generate illegal LLVM intrinsics, even if 
the input program is horribly broken (like 126.gcc).

b13b431a6e Added check for target machine endian-ness and put the result into 
Makefile.config (ENDIAN variable is set to big or little).

declarations.

fbacee0077 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.

 2004-02-13 17:03:01 +00:00
Chris Lattner
2265790f9f 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!

to an unsigned char so that overall MachineInstr's size stays the
same.
