They used to be called "define_mode_macro" and "define_code_macro".
For this testcase:
void g(const unsigned char b)
{
unsigned short c = b & 0xff;
}
we get:
wconversion-3.c:3: warning: conversion to 'unsigned char' from 'int'
may alter its value
wconversion-3.c:3: warning: conversion to 'short unsigned int' from
'int' may alter its value
Really weird... It is

Done as requested, see
I can't seem to find a concrete answer anywhere to this: does the
current version of gcc support building executables for the 64 bit
version of Windows?
I am using gcc through MinGW and using the -m64 option results in a
"sorry, unimplemented: 64-bit mode not compiled in" message.
Thanks,
Ali.

Sorry, I don't know when they were first introduced, but if you can't find
them in
Dave,
Is is only for 4.3+? Define_mode_iterator is not recognized in 4.2.1 I
am working on. And I didn't find anything in GCC4.2.1 internal manual
either.
Cheer.

Consider the following code:
f.cc ==>
void f(const unsigned char b)
{
unsigned char c = static_cast(b & 0xff);
}
<== f.cc
Compile with g++ 4.1.2:
$ g++-4.3-20071109 -c f.cc -Wconversion
$
Note no warnings.
Compile with g++ 4.3-20071109:
$ g++-4.3-20071109 -c f.cc -Wconversion
f.cc:
Hi,
I am writing instruction patterns for vector modes (V4Si, V8HI, V16QI,
etc). Since these modes have the same length, the underlying
instructions may also be the same (load/store instrucitons, AND/OR
instructions, etc). Is there any simple way to combines patterns for
different modes instead
