floating-point MATH_LIB. The sa_time.a/.ada file provides the

Elapsed_Time_Of( ) function.

The purposes of the more important specification files are listed in

Table 3-3.

Data Types

Several of the target-specific utilities are involved with data types; three

data types (declared in

sa_types.a/ada) are defined for the Ada Code

Generator:

RT_FLOAT Corresponds to Ada type FLOAT.

RT_INTEGER Corresponds to Ada type INTEGER.

RT_BOOLEAN Corresponds to Ada type BOOLEAN.

At compilation, you must make available the specification file

sa_types_.a (or sa_types_.ada), which declares these types, along

with corresponding array types. This file is in the source distribution

directory on your system and you can edit a copy of the file as required.

Certain global record, array, and exception types are also defined in

this file. The record type

RT_STATUS_RECORD is declared in

sa_types_.a/.ada and is used when UserCode Blocks are referenced.

File Purpose

sa_types_.a

Defines the supported data types.

sa_defn_.a

Defines constants and error codes for generated code.

sa_utils_.a

Defines external function prototypes for the

stand-alone utilities.

sa_math_.a

Defines special math functions used by generated

code.

sa_fmath_.a

Used only by Verdix compilers to re-export functions

already supported by the Ada math library.

sa_time_.a

Declares time-related variables and functions.

sa_user.a

Defines function prototypes for UCBs.
