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. |
