Bug ID: 98857
Summary: Add support for function attributes applied to
function pointers from non-capturing lambdas
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

example
Since non-capturing lambda has to be convertible to a function pointer it may
be useful to be able to specify function attributes (such as
[[gnu::aligned(N)]]) which apply to the function pointer obtained from such
lambda.
Example use: https://godbolt.org/z/ds1G6z
(also attached)
Although this opens some questions about which attribute applies to any of the:
1) lambda object
2) member application function: &decltype(lambda)::operator()
3) function pointer from non-capturing lambdas
and where to place the attribute specifier.
