Hi Richard:
Test with x86 and rl78, both are rejected by the front-end if modes
are different from Pmode/ptr_mode,
so I'm gonna commit this change :)
Testcase for x86 / x86_64:
```
void test(void)
{
int __seg_fs *f = (int __seg_fs *)16;
int __seg_fs *g = (int __seg_fs *)32;
Hi,
As PR102658 shows, commit r12-4240 enables vectorization at O2,
some cases need to be adjusted accordingly for rs6000 port.
- For target specific test cases, this adds -fno-tree-vectorize
to retain original test points, otherwise vectorization can
make some expected scalar instructions gone

So here is the GCC 10 branch version which fixes the wrong code.
The problem is we create a negation of an one bit signed integer type
which is undefined if the value was -1.
This is not needed for GCC 11 branch since the case is handled differently
there and has been fixed
This option is enabled by default when -Wformat option is enabled. A
user can specify -Wno-format-int-precision to disable emitting
warnings when passing an argument of an incompatible integer type to
a 'd', 'i', 'o', 'u', 'x', or 'X' conversion specifier when it has
the same precision as the
An output constraint takes a lvalue. While GCC happily strips the
incorrect lvalue to rvalue conversion, Clang rejects the code by default:
error: invalid use of a cast in a inline asm context requiring an lvalue:

Changes in v4:
1. Bypass redundant check when inputs have been transformed to the
equivalent canonical form with valid bit operation.
Changes in v3:
1. Check invalid bit operation.

Hi Jason,
Hope you are well. Thanks for the feedback.
