Note that this indicates a serious problem with the way we are emitting varargs, but this should not be properly fixed until after 1.3. This patch SHOULD go into 1.3. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15602 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-25Temporarily disable this code, as it is emitting LLVM_NAN("nan") which ↵Chris Lattner
results in a call to the glibc 'nan' function because the initializer is not a string. This breaks when used in a global initializer. Try compiling this testcase for example: %X = global float <some nan value> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15223 91177308-0d34-0410-b5e6-96231b3b80d8

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

2004-02-26Fixes 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

2004-02-15Now 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

2004-02-13Convert 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

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
