* Do not generate by TableGen the hard-coded standard, target-independent part ofRoman Levenstein2008-05-142-140/+195
| | | | | | | | | | | | | | | | DAG instruction selectors. Introudce a dedicated header file for this part: include/llvm/CodeGen/DAGISelHeader.h TableGen now only generates the include preprocessor directive to include this new header. This is a preparation for supporting multiple implementations of instruction selectors in the future.

| | | | | | | | | | | | Do not rely on std::swap<Use>, provide a (faster) member function instead.

* Adding files for Microchip's PIC16 target.Sanjiv Gupta2008-05-1323-0/+3323
| | | | | | | | | | | | | | | | | | | A brief description about PIC16: =============================== PIC16 is an 8-bit microcontroller with only one 8-bit register which is the accumulator. All arithmetic/load/store operations are 8-bit only. The architecture has two address spaces: program and data. The program memory is divided into 2K pages and the data memory is divided into banks of 128 byte, with only 80 usable bytes, resulting in an non-contiguous data memory. It supports direct data memory access (by specifying the address as part of the instruction) and indirect data and program memory access (in an unorthodox fashion which utilize a 16 bit pointer register). Two classes of registers exist: (8-bit class which is only one accumulator) (16-bit class, which contains one or more 16 bit pointer(s)) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51027 91177308-0d34-0410-b5e6-96231b3b80d8
