Compiler Directives

HP pTAL Reference Manual—523746-006

17-38

GP_OK

causes the pTAL compiler to generate code that has GP-relative addressing

(“small” data).

NOGP_OK

suppresses the generation of code that has GP-relative addressing. (This is the

only option for the EpTAL compiler.)

PUSHGP_OK

pushes the current setting (GP_OK or NOGP_OK) onto the GP_OK directive

stack. Does not change the current setting.

POPGP_OK

pops the top value from the GP_OK directive stack and changes the current setting

to that value.

For an explanation of directive stacks, see Directive Stacks on page 17-4.

A pTAL program that references data in a shared run-time library (SRL) must specify

NOGP_OK when it declares a data block that belongs to a shared run-time library. This

Note. The EpTAL compiler ignores these directives.

Default: pTAL compiler: GP_OK

EpTAL compiler: NOGP_OK

Placement: Anywhere except inside a data block or inside a procedure declaration

Scope:

•

GP_OK applies to subsequent code it until it is overridden by

NOGP_OK

•

NOGP_OK applies to subsequent code until it is overridden by

GP_OK

Dependencies: Do not use GP_OK with CALL_SHARED
