2010-10-11Per discussion with Sanjiv, remove the PIC16 target from mainline. When/ifChris Lattner
it comes back, it will be largely a rewrite, so keeping the old codebase in tree isn't helping anyone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116190 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Normalize Subtarget constructors to take a target triple string instead ofDaniel Dunbar
Module*. Also, dropped uses of TargetMachine where unnecessary. The only target which still takes a TargetMachine& is Mips, I would appreciate it if someone would normalize this to match other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77918 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Added a more function PIC16 backend. However to get this working a patch inSanjiv Gupta
ExpandIntegerOperand (LegalizeIntegerTypes.cpp) is needed which is yet to be reworked and submitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59617 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-14Detabification. Fixed indentation and spacing.Sanjiv Gupta
Changed cout to DOUT, and TODOs to FIXMEs. Other changes as per coding conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51105 91177308-0d34-0410-b5e6-96231b3b80d8

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
