ISO Standard: |
“The extent to which suggestions made by using the register
storage-class specifier are effective (C90 6.5.1, C99 6.7.1).” |
Implementation: |
The register storage class specifier generally has no effect. |
ISO Standard: |
“The extent to which suggestions made by using the inline function
specifier are effective (C99 6.7.4).” |
Implementation: |
If -fno-inline or -O0 are
specified, no functions will be inlined, even if specified with the
inline specifier. Otherwise, the function may or may not be
inlined dependent on the optimization heuristics of
the compiler. |
