◆ PCL_CDECL

◆ PCL_CONDITION_UNLIKELY

#define PCL_CONDITION_UNLIKELY ( x ) (x)

Tries to inform the compiler to optimize codegen assuming that the condition will probably evaluate to false.

Note: Prefer using PCL_{IF,WHILE}_UNLIKELY

Warning: This can't be used with switch statements

This tries to help the compiler optimize for the unlikely case. Most compilers assume that the condition would evaluate to true in if and while loops (reference needed) As such the opposite of this macro (PCL_CONDITION_LIKELY) will not result in significant performance improvement

Some sample usage:

if PCL_CONDITION_UNLIKELY(x == 0) { return; } else { throw std::runtime_error("some error"); }
//
while PCL_CONDITION_UNLIKELY(wait_for_result) { sleep(1); }  // busy wait, with minimal chances of waiting

      major_version_mismatch)

macro for compatibility across compilers and help remove old deprecated items for the Major.Minor release

compiler errors of unneeded_deprecation and major_version_mismatch are hints to the developer that those items can be safely removed. Behavior of PCL_DEPRECATED(1, 99, "Not needed anymore")
