* Add support for a cycle counter intrinsic. As basically all processors haveAndrew Lenharth2005-11-112-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this and have it in about the same form, I think this makes sense. on X86, you do a RDTSC (64bit result, from any ring since the P5MMX) on Alpha, you do a RDCC on PPC, there is a sequence which may or may not work depending on how things are setup by the OS. Or something like that. Maybe someone who knows PPC can add support. Something about the time base register. on Sparc, you read %tick, which in some solaris versions (>=8) is readable by userspace on IA64 read ar.itc So I think the ulong is justified since all of those are 64bit. Support is slighly flaky on old chips (P5 and lower) and sometimes depends on OS (PPC, Sparc). But for modern OS/Hardware (aka this decade), we should be ok. I am still not sure what to do about lowering. I can either see a lower to 0, to gettimeofday (or the target os equivalent), or loudly complaining and refusing to continue. I am commiting an Alpha implementation. I will add the X86 implementation if I have to (I have use of it in the near future), but if someone who knows that backend (and the funky multi-register results) better wants to add it, it would take them a lot less time ;) TODO: better lowering and legalizing, and support more platforms git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24299 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow per-character control over what target assemblers allow in symbolChris Lattner2005-11-101-0/+17

If you don't want this, use markCharUnacceptable to remove one of these or markCharAcceptable to add to the set. This corresponds with what GAS accepts by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24291 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | This eliminates the vector, allows constant time removal of a node from a graph, and makes iteration over the all nodes list stable when adding nodes to the graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24262 91177308-0d34-0410-b5e6-96231b3b80d8
