2004-06-02<alloca.h> on cygwin pulls in a ton of stuff (macros and function protos)Chris Lattner
that we REALLY don't want in the CBE code. With this fix, the CBE passes all of the MultiSource tests on cygwin that it does on linux. Yaay! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13975 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-28Fix the big regression that has been killing the nightly tester these lastChris Lattner
few days. Apparently the old symbol table used to auto rename collisions in the type symbol table and the new one does not. It doesn't really make sense for the new one to do so, so we just make the client do it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13877 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-20Fix to make the CBE always emit comparisons inline. Hopefully this willChris Lattner
fix the really bad code we're getting on PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13609 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-09syntactically loopify natural loops so that the GCC loop optimizer can find ↵Chris Lattner
them. This should *dramatically* improve the performance of CBE compiled code on targets that depend on GCC's loop optimizations (like PPC) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13438 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-09Do not emit prototypes for setjmp/longjmp, as they are handled speciallyChris Lattner

2004-05-09Make the floating point constant pools local to each function, split theChris Lattner
FindUsedTypes manipulation stuff out to be a seperate pass, and make the main CWriter be a function pass now! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13435 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-27Changes to fix up the inst_iterator to pass to boost iterator checks. ThisChris Lattner
patch was graciously contributed by Vladimir Prus. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13185 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-01Add support for select constant expressions to the CBE, fixing SIODChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12589 91177308-0d34-0410-b5e6-96231b3b80d8
2004-03-13Rename the intrinsic enum values for llvm.va_* from Intrinsic::va_* toChris Lattner
Intrinsic::va*. This avoid conflicting with macros in the stdlib.h file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12356 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-26Fixes for PR258 and PR259.John Criswell
Functions with linkonce linkage are declared with weak linkage. Global floating point constants used to represent unprintable values (such as NaN and infinity) are declared static so that they don't interfere with other CBE generated translation units. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11884 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-24Fix some unexpected fallout from the config.h changes. Because the CBE noChris Lattner
longer was getting this #include, it always fell back on the less precise floating point initializer values, causing some testsuite failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11803 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-20It is totally unacceptable to print out (literally) millions of zeros whenChris Lattner
compiling 129.compress... so don't! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11649 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-15Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, someChris Lattner
hacks can be banished. Also, this gives us the opportunity to emit special code for the setjmp/longjmps which alows the elimination of one GCC warning for every setjmp/longjmp site (which is often THOUSANDS in C++ programs). Yaay! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11484 91177308-0d34-0410-b5e6-96231b3b80d8

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

getElementTypes() is gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11228 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-10Upon Chris's suggestion, moved the #ifdef's to the generated C code.John Criswell

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

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
