Cygwin gcc 4.5.3
I have run some tests to determine the gcc 4.5.3 integer promotion policies.
The
tests show that for 'char' input, "char << long" and "char >> long" promote to
INT while other operations using a long promote to" long", and that "char <<
ulong" and "char >> ulong" promote to INT while other operations using ulong
promote to "ulong". In similar fashion, "long << long" and "long >> long"
promote to INT while other promotions are to long, and that "long << ulong" and
"long >> ulong" promote to long while other operations promote to ulong. The
code used and the output are included below.
The code is not production code.
I think the code is correct and that my interpretation is also correct. I
realize that gcc 4.5.3 is no longer supported so if my guess is correct do I
have to switch to mingw (for precompiled later compilers)?
