debugging information

Name, type, source ￿le, and source-line-to-address mapping information generated by the compiler for use by the debugger. This information can signi￿cantly increase the size of an executable ￿le. All debugger information is preprocessed (and reduced in size) when the program is linked.

`declared block

Outer debugger block used to contain de￿nitions of user-declared symbol names. You may explicitly refer to symbol names created using the declare command by using a block quali￿ed name.

de￿ne macro

See macro.

 

delay slot

 

The instruction following a branch instruction. In PA-RISC assembly

Glossary

language, a branch instruction is paired with the instruction that follows it, and both are executed simultaneously. When you step through assembly code, this means that when you reach the branch instruction (the BL instruction in the following example), you do not immediately step into the routine read_sequence . Instead, you step to the next instruction (LDO), and the next time you step, both the branch and the load occur.

BL

read_sequence,%r2

LDO

-272(%r30),%r24
