#2000: -funfolding-update-in-place badly documented
-------------------------+--------------------------------------------------
Reporter: m4dc4p | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.8.1
Severity: normal | Keywords:
Difficulty: Unknown | Testcase:
Architecture: x86 | Os: Windows
-------------------------+--------------------------------------------------
The documentation for -funfolding-update-in-place implies it takes a
numeric argument:
-funfolding-update-in-place=n
Switches on an experimental "optimisation". Switching it on makes the
compiler a little keener to inline a function that returns a constructor,
if the context is that of a thunk.
But in fact it does not. Either the documentation is wrong or the
implementation has a bug, as compiling with -funfoling-update-in-place=10
gives an error that the flag is not recognized.
