* TargetCacheInfo has been removed; its only uses were to propagate a constantBrian Gaeke2004-03-011-1/+0
| | | | | | | | | | (16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in the interest of not breaking things any more than they already are, I'm going to leave the constant alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12043 91177308-0d34-0410-b5e6-96231b3b80d8
* Fixes for PR258 and PR259.John Criswell2004-02-262-6/+6
| | | | | | | | | | 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
* Fix some unexpected fallout from the config.h changes. Because the CBE noChris Lattner2004-02-242-0/+2
| | | | | | | | 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

* Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, someChris Lattner2004-02-152-4/+30
| | | | | | | | | 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).
