* Several fixes to handling of int CC register:Vikram S. Adve2003-07-102-16/+20
| | | | | | | | | | | | | | | | | | | | | | (1) An int CC live range must be spilled if there are any interferences, even if no other "neighbour" in the interf. graph has been allocated that reg. yet. This is actually true of any class with only one reg! (2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must be spilled so that the machine-independent spill code doesn't have to make the machine-dependent decision of which CC name to use based on operand type: %xcc or %icc. (These are two halves of the same register.) (3) LR->isMarkedForSpill() is no longer the same as LR->hasColor(). These should never have been the same, and this is necessary now for #2. (4) All RDCCR and WRCCR instructions are directly generated with the phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to deal with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7152 91177308-0d34-0410-b5e6-96231b3b80d8

* Corrected the Table of Contents.John Criswell2003-07-081-153/+238
| | | | | | | | | | | | | | | | Corrected capitalization of subheadings. Created a new subsection for compiling the C front end and moved all references to it there. Updated the disk space requirements to reflect the need for the binary C front end and the optional C front end source. Added information on unpacking the distribution to the summary section. Moved autoconf environment variables to the autoconf section. Changed make to gmake. Removed some of the precise directions for unpacking the archives. Fixed some formatting inconsistencies (headings that were not centered). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7132 91177308-0d34-0410-b5e6-96231b3b80d8

* Apparently, the "regType" and "regClass" used in the Sparc backend are not bothMisha Brukman2003-07-032-42/+95
| | | | | | | | | | | | correct: empirically, "regType" is wrong for a number of registers. Thus, one can only rely on the "regClass" to figure out what kind of register one is dealing with. This change switches to using only "regClass" and adds a few extra DEBUG() print statements and a few clean-ups in comments and code, mostly minor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7103 91177308-0d34-0410-b5e6-96231b3b80d8
