HP aC++/HP C Programmer's Guide (B3901-90036; A.06.26; September 2011)

If $DISPLAY is set, the default web browser is used. If the display variable is not set, a
message is displayed. Set your $DISPLAY variable as follows:
export DISPLAY=YourDisplayAddress (ksh/sh shell notation)
setenv DISPLAY YourDisplayAddress (csh shell notation)
Examples:
To use a browser other than the default, first set the BROWSER environment variable to
the alternate browser’s location:
export BROWSER=AlternateBrowserLocation
To invoke the online guide, use the command:
aCC +help
Inlining Options
These options allow you to specify the amount of source code inlining done by HP aC++.
+inline_level num
+inline_level num
The +inline_level option controls how C/C++ inlining hints influence aCC or cc.
Such inlining happens in addition to functions that are explicitly tagged with the inline
keyword. (For C89, use the __inline keyword). This option controls functions declared
with the inline keyword or within the class declaration, and is effective at all
optimization levels.
NOTE: The +d and +inline_level 0 options turn off all inlining, including implicit
inlining.
The format for num is N [. n ], where num is either an integral value from 0 to 9, or a value
with a single decimal place from 0.0 to 9.0, as described in the following table:
Description num
No inlining is done (same effect as the +d option).0
Only functions marked with the inline keyword or implied by the language to be
inline are considered for inlining.
1
This is the default for C++ at +O1.
Increasingly makes inliner more aggressive below 2.0.1.0 < num <
2.0
Provides more inlining than level 1. This is the default level at optimization levels +O2,
+O3, and +O4.
