IOBYTE 46f3f58e5f Fix #9388 ("debug: Executable scope 'x' with unknown function." with alias used in initialization list) (#2239) 2019-10-05 09:34:37 +02:00
IOBYTE c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
I fixed the AST enough to pass testrunner but I don't believe it is
correct.

This code:

void Foo4(int&&b);

has this AST:

( 'void'
|-Foo4
`-&& 'bool'
  |-int
  `-b 'signed int'

but I don't believe && should have `bool`.

Rikard Falkeborn 4dbf006dc7 Fix severity of c++14 shifts with too many bits (#2213)
For c++14, shifting a variable with a value larger than or equal to the
number of bits in the variable is undefined. Left-shifting with a value
equal to the number of bits of the variable is implementation defined.

See also trac ticket #9306.
