New Features in Version B.11.11.10

HP C compiler version B.11.11.10 supports the following new features:

• Function Inlining

• +d Option

• UNIX95 Feature

Function Inlining

Now function inlining happens at all optimization levels, by default. Functions that should be

inlined by the compiler need to be tagged with the __inline keyword in -Ae mode (inline,in

-AC99 mode).

+d Option

This option disables function inlining at optimization levels less than +O3. Refer to Function

Inlining for more information.

UNIX95 Feature

Previously, if a search directory speciﬁed for -I or -L did not exist or was invalid, the cc driver

would ignore it silently and the compilation would proceed. This is inappropriate, since an

incorrect alternate library or include directory speciﬁed on the command line to override a

system one will never be detected.

Now, on encountering a search directory on the command line, which, either does not exist or

has invalid permissions, an error is ﬂagged and the compilation is aborted. This behavior is

applicable only in strict ANSI mode when either UNIX_STD=95 or UNIX_STD=98 or UNIX95=1

has been set in the environment and only when the compiler has been invoked as c89.
