### 6.1 Register Conventions

The compiler has different register conventions, depending on the target processor used; some of the registers have specific uses during code generation. The following section describes the generic names of the registers on a platform per platform basis. It also indicates what registers are used as scratch registers, and which can be freely used in assembler blocks.

6.1.1 accumulator register
6.1.2 accumulator 64-bit register
6.1.3 float result register
6.1.4 self register
6.1.5 frame pointer register
6.1.6 stack pointer register
6.1.7 scratch registers
6.1.8 Processor mapping of registers
