HP aC++/HP C A.06.20 Programmer's Guide

NOTE: When using -ext, specify it at both compile and link time. For example:
aCC -ext foo.C
compiles foo.C which contains a long long declaration.
#include <iostream.h>
void main(){
long long ll = 1;
cout << ll << endl;
}
+e
The +e option is equivalent to the -ext option.
Floating-Point Processing Options
The following command-line options are used for floating-point processing.
+O[no]cxlimitedrange
+O[no]cxlimitedrange
The +O[no]cxlimitedrange option enables [disables] the specific block of codes
with the usual mathematical formulas. This option is equivalent to adding the pragma:
#pragma STDC CX_LIMITED_RANGE
The default is +Onocxlimitedrange.
+O[no]fenvaccess
+O[no]fenvaccess
The +O[no]fenvaccess option provides a means to inform the compiler when a
program might access the floating-point environment to test flags or run under
non-default modes.
Use of the +Onofenvaccess option allows certain optimizations that could subvert
flag tests and mode changes such as global common subexpression elimination, code
motion, and constant folding. This option is equivalent to adding #pragma STDC
FENV_ACCESS ON at the beginning of each source file submitted for compilation.
The default is +Onofenvaccess.
-fpeval
-fpeval=precision
