number leads it to consider more candidates. The inlining candidates are ordered in
priority order based on the inliner’s heuristics, so this does not affect the most important
candidates.
The +Oinlinebudget option controls the aggressiveness of inlining according to the
value you specify for n where n is an integer in the range 1 - 1000000 that specifies the
level of aggressiveness, as follows:
n= 100 Default compile time budget.
n> 100 Allows the inliner to consider more candidates and increase compile time.
n<100 Considers fewer candidates to reduce compile time for the inliner.
The +Onolimit and +Osize options also affect inlining. Specifying the +Onolimit
option has the same effect as specifying +Oinlinebudget=200. The +Osize option
has the same effect as +Oinlinebudget=1.
NOTE: The +Oinlinebudget option takes precedence over both of these options.
This means that you can override the effect of +Onolimit or +Osize option on inlining
by specifying the +Oinlinebudget option on the same compile line.
Use this option at optimization level 2 or higher.
The default is +Oinlinebudget=100.
+Olit
+Olit=kind
The +Olit option places the data items that do not require load-time or runtime
initialization in a read-only data section. +Olit=all is the default for both HP aC++
and HP C. This represents a change from earlier versions of the HP C compiler, which
defaulted to +Olit=const. Note that if you attempt to modify the constant or literal,
a runtime signal 11 will be generated.
The defined values for kind are:
all
All string literals and all const-qualified variables that do not require load-time
or runtime initialization will be placed in a read-only data section. +Olit=all
replaces the deprecated +ESlit option.
const All string literals appearing in a context where const char * is legal, and
all const-qualified variables that do not require load-time or runtime
initialization will be placed in a read-only data section. +Olit=const is
mapped to +Olit=all with a warning, except in C mode. +Olit=const
replaces the deprecated +ESconstlit option in C.
none
No constants are placed in a read-only data section. +Olit=none replaces
the deprecated +ESnolit option.
