I'm getting a lot of errors from the assembler "non-constant .uleb128 is
not supported" when trying to bootstrap the compiler with the
cross-compiled ada compiler.

Hi!
So, apparently I've misread when exceptions are raised by
nextafter/nexttoward (and errno set).
if(((ix>=0x7ff0)&&((ix-0x7ff0)|lx)!=0) || /* x is nan */
((iy>=0x7ff0)&&((iy-0x7ff0)|ly)!=0)) /* y is nan */
return x+y;
I believe the above only

With GNAT you can declare a function as pure with a dedicated pragma, even if
it takes a parameter passed by reference. In this case, if the parameter is
declared as In (the default), the language additionally guarantees that it is

These actual subtypes are artificial subtypes generated for parameters whose
nominal subtype is an unconstrained array type in order to expose the bounds.
There is no point in generating debug info for them so avoid doing it now.

This reduces the number of false positives of -Wstack-usage in the presence of
variables whose nominal subtype is a discriminated record with a variant part.

Thanks to Eric Botcazou, this eliminates almost all of the remaining Ada
testsuite failures by adding a missing definition for the target specific
handling of function descriptors.
Tested with a native riscv64-linux bootstrap with Ada, and running the Ada
testsuite. There are only 4 failures left

Not if the compiler was built in a canadian cross. That's the only way
to bootstrap an Ada compiler.

Needed one more tweak; when dealing with a capture proxy, always bail
out and never fall through to the warning-handling
code below the DR 2211 check.

While working on other string folding improvements (PR 77357)
I came across another distinct case where GCC could do better:
it doesn't consider as candidates strings that have as many
elements as the size of the array they are stored in, even if
their length is within the bounds of the array. Fo

That Ada compiler is unique in that it uses exceptions.
