Hi,
This fixes a fallout that actually goes back to 5.0 but went unnoticed.
The costs for movt and movrt type of insns were not correctly reported
and ifcvt thus made some bad choices for SH. A new cset_zero pattern
variant is also required to fix the matching for some recent changes
in the middl
Hi!
This patch makes -Wint-in-bool-context warn on suspicious integer left
shifts, when the integer is signed, which is most likely some kind of
programming error, for instance using "<<" instead of "<".
The warning is motivated by the fact, that an overflow on integer shift
left is undefined be
Hi,
this patch fixes PR77558, an ice-on-invalid-code 6/7 regression.
The fix for PR71602 introduced the invalid-code test-case

Hi!
Currently CHECKING_P is not a boolean flag but a ternary option.
However the _P in the name implies it is a boolean.
That should be cleaned up again IMHO.
So this patch splits CHECKING_P into CHECKING_P and a new flag
ENABLE_EXTRA_CHECKING. All uses of CHECKING_P are actually of
the form

Today I traced AVX2 optimisation bug in gcc and
distilled it down to '__builtin_ia32_gatheraltdiv4si256'
generated by gcc.
When I attempted to use this builtin directly
in a simple program gcc refused to recognise
it as known:
#include

Is the above change really necessary? Would be nice to get rid of this
extra code. The rest looks OK to me.
