8 Error and Warning Messages

OCA issues an error or warning message when it finds a code construct that it cannot

accelerate, or when it cannot understand input options or input file format. OCA does

not produce an executable object file if it finds error conditions. You must resolve all

error conditions to accelerate your program successfully.

This section documents OCA warning and errors. It also describes recovery

procedures, when appropriate, from problems that OCA detects.

Error and warning messages appear in summary form in the OCA output listing.

Warning Messages

OCA issues a warning when it finds a code construct for which it might have produced

incorrect code. OCA cannot automatically distinguish between a benign situation and a

dangerous situation, so you must check the code manually as recommended by the

specific message. An OCA session that produces warnings also produces an

executable file. Investigate the cause of each warning to make sure that the

accelerated file will execute correctly.

Cause. This message displays in TAL programs when TNS code appears to

reference a register before setting a value in that register. In TAL programs, the USE,

STACK, and CODE statements can be used to write procedures that implicitly pass

parameters in the TNS register stack. HP discourages this practice and it is not

supported in accelerated customer code. OCA assumes that procedure parameters

are pushed on the memory stack and that the TNS registers are pushed on the

memory stack. The values in the TNS registers are not subsequently used by the

called procedure. When a procedure references a register before resetting it, it is said

to “inherit a register” because the value in the referenced register must have been

inherited from a calling procedure. See Register Inheritance Diagnosis for more

information.

Effect. OCA accelerates this program despite the message. This message can

sometimes display when inheriting a register has not occurred. For example, there may

be no inheritance of registers if the procedures makes a call to Debug or if the caller

Note: OCA options are not case-sensitive, but procedure names

are case-sensitive. To avoid an error, procedure names must

match the names in an object file exactly.
