2004-02-14Use intrinsic lowering like the rest of the backends. Get rid of crufty hackyChris Lattner
code that worked around problems in the mangler git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11426 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Convert the C backend into a target, for use with LLC. This allows us to useChris Lattner
the lowerallocations pass to eliminate malloc/free warnings and hackish code git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11409 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Make the cwriter use the lowerinvoke pass so that it can either use ↵Chris Lattner
"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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11405 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-12Add support for memcpy and memmove intrinsics. Why isn't the cwriter usingChris Lattner
the intrinsiclowering code?? :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11362 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-09Adjust to the changed StructType interface. In particular, ↵Chris Lattner
getElementTypes() is gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11228 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-11Turn off "attribute weak" to pacify Mac OS X's system compiler, which prints aBrian Gaeke
warning whenever it sees it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10391 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-10Upon Chris's suggestion, moved the #ifdef's to the generated C code.John Criswell
This makes LLVM and the generated C code more portable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10377 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-10Fixed the CBE on Solaris/Sparc. We need to define the return value ofJohn Criswell
the write() system call because it returns 64 bits on Solaris 64 bit, and an implicit return value of int says it returns 32 bits. Admittedly, this is a bit of a hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10375 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10167 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-16ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automaticChris Lattner
storage duration that are local to the function containing the invocation of the [...] setjmp macro that do not have volatile-qualified type and have been changed between the setjmp invocation and longjmp call are indeterminate." As such, we have to mark all variables in a function that uses 'invoke' as volatile. This fixes PR77 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10035 91177308-0d34-0410-b5e6-96231b3b80d8

2003-11-03This simplifies the CWriter code, makes the generated code easier to read,Chris Lattner
and makes the output work with the intel compiler. Overall, a win. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9671 91177308-0d34-0410-b5e6-96231b3b80d8

2003-11-02The "correct" fix for CBackend/2003-10-23-UnusedType.ll is to not even tryChris Lattner
to emit types which are not used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9647 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-12* Spell "necessary" correctlyChris Lattner
* Print floating point values using C99 hexadecimal style FP if possible. This increases the number of floating point constants that may be emitted inline, and improves precision for global variable initializers which can not be emitted in integer form. This fixes the Olden/Power benchmark with the CBE!!!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9052 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-12* Be TBAA safeChris Lattner
* Fix isFPCSafeToPrint to find more constants safe to print, which it was failing because ftostr was padding with leading space characters. * Scan the entire module for global constants instead of each function at a time. This has the advantage of allowing us to emit constants at global scope instead of function scope. This speeds FP programs quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9048 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-05A couple of minor code cleanups.Chris Lattner

2003-07-31Modified the code so that it generates (0) for setjmp() and abort() forJohn Criswell
longjmp() (and does not include setjmp.h). This is to fix some problems on Sparc while non-local jumps are still unimplemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7449 91177308-0d34-0410-b5e6-96231b3b80d8
