Subject: [Patch, Fortran] PR34246 - Fix for character bind(C) functions
Date: Sun, 09 Dec 2007 22:40:00 -0000 [thread overview]
Message-ID: <475C6EEC.10601@net-b.de> (raw)

I implemented a while a go a patch which should generate for
character(len=1,kind=c_char) function foo() bind(C)
an interface matching the C prototype
char foo()
However, the test case failed on some systems (e.g. working on x86-64
but failing on x86-32). It turned out that the returned value was still
regarded as array by the middle end.
The attached patch fixes this; as the patch was created on a
try-and-error bases, it should be carefully reviewed.
Build and regression tested (check-gfortran + gomp) with -m32 and -m64
on x86-64-linux.
OK for the trunk?
Tobias
