digitalmars.D - DMD and SIMD Bugs

reply Walter Bright <newshound2 digitalmars.com> writes:
There have been some complaints about the SIMD bugs in DMD, so I thought I'd 
have a look and see what can be done. I've fixed several issues (for dmd, 
excluding the library and enhancement requests), these are the remainder:

If your bug was filed and was neither fixed nor on that list, please tag with 
the SIMD keyword.

If your bug was not filed, it won't be fixed, so sad, too bad!

Please take a look at 20041; it's awful. It would be really nice 
if this actually worked, but even an ICE would be preferable to 
what it actually does:

Ok, I'll have a look. (It's a problem in the front end, not DMD specific, hence 
affects all D compilers.)

Great, thanks! This will make it *so* much easier to use SIMD in 
D without accidentally shooting oneself in the foot.

Currently happy with the current state of master, thanks for the 
recent fixes!
Planning to add actual D_SIMD usage in intel-intrinsics so that 
DMD is not artificlally behind.
It's a lot of work to do so if anyone is attracted by unusually 
repetitive and detail-oriented work don't hesitate (particularly 
for SSSE3, SSE4.1, SSE4.2 any help will help)

It's easier to work on the bunch when they are closely related.
