* Add support alignment of allocation instructions.Nate Begeman2005-11-051-9/+12
| | | | | | | | | Add support for specifying alignment and size of setjmp jmpbufs. No targets currently do anything with this information, nor is it presrved in the bytecode representation. That's coming up next. llvm-svn: 24196
* When a function takes a variable number of pointer arguments, with a zeroJeff Cohen2005-10-231-4/+4
| | | | | | | | | | | | | pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. llvm-svn: 23888

* Completely rewrite 'correct' eh support. This changes how setjmp insertionChris Lattner2005-09-271-140/+301
| | | | | | | | | | | | | | | | | is performed so it is only at most once per function that contains an invoke instead of once per invoke in the function. This patch has the following perks: 1. It fixes PR631, which complains about slowness. 2. If fixes PR240, which complains about non-volatile vars being live across setjmp/longjmps. 3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not forcing the jmpbufs to always be 8-bytes off the alignment of the structure. 4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us now about 4% faster than GCC. Further improvements are also possible. llvm-svn: 23477
* The correct fix for PR612, which also fixesChris Lattner2005-08-031-2/+12
