HP aC++/HP ANSI C Release Notes (B3901-90037; A.06.26; September 2011)

#pragma diag_pop (New)
This pragma restores the severities of all diagnostics to the state prior to the last #pragma
diag_push. A compilation unit should have an equal number of #pragma diag_push
and #pragma diag_pop uses.
+Oinlinebudget is deprecated (Change)
The +Oinlinebudget option is deprecated in this release and will not be supported
in future releases. Use +inline_level.
In next release, default C compilation mode will change from C89 to C99
In the next version of the HP C/aC++ compiler, the default C compilation mode will
change from C89 to C99. So cc -Ae or aCC -Ae will be the same as -AC99, and
C99 features will be enabled.
Users can prepare for this transition by adding -AC99 to their build options and
addressing any issues. Errors that can happen with -AC99 include:
• enum out of range:
error #2066: enumeration value is out of "int" range
error #4041: enumeration value is out of "char" range
• Restriction on constant expressions:
error #2057: this operator is not allowed in a constant expression
error #2028: expression must have a constant value
Was this:
warning #4045-D: non-constant initialization performed at runtime
• Non-static inline can't reference static:
error #3031-D: an entity with internal linkage cannot be referenced
within an inline function with external linkage
• Use of inline or restrict as variables/functions/types. New diagnostics will
be added to warn users about the use of inline and restrict in this release
(A.06.20). For example:
4347 %s is a keyword in the C99 C Standard, and its usage as an
identifier will cause an error in C99 mode
In next release, default C++ compilation mode will change to full -AA
In the next version of the HP C/aC++ compiler, the default C++ compilation mode will
change from almost -AA to -AA. This will enable -Wc,-ansi_for_scope,on. This is
being done to reduce porting efforts by meeting the C++ Standard.
Users can prepare for this transition by adding -AA to their build options and addressing
any issues. Errors and warnings (with unintended runtime results) that can happen with
-Wc,-ansi_for_scope,on include:
• Loop index is no longer in scope after the for loop body:
