Enhancements and Defect Fixes
This section describes enhancements and defect fixes in the HP ANSI C compiler. Version
B.11.11.06 of the HP C/ANSI C compiler has the following enhancements/defects fixed:
• JAGae13383: -mt option needed similar to aCC
• JAGae20847: UTF-16 support for HP C compiler.
• JAGae13389: Support for +ub option to make unqualified bit fields
unsigned by default.
• JAGad96950: Support for OpenMP single pragma with clauses.
Workarounds
The following are workaround solutions to previous problems with the HP C/ANSI C
compiler:
• +Onomoveflops should always be used with the +FPZ and +FPI floating point options.
+Onomoveflops prevents floating point instructions from being moved, and replaces
integer division by floating point multiply by the inverse.
• If you intend to use GNU style variable argument macros in HP C, note that you can
make the concatenation operator ## prevent syntax errors from occurring when the
variable argument comes in as empty (the null string).
