Nested instruction patterns rejected by GlobalISel when having registers in Defs
...itional results. I am tempted to modify that part of the
code, but maybe Im missing some invariant thats not immediately evident
Cheers,

Hi Gabriel,
I'm working on a downstream target which uses GlobalISel and we have many
patterns with instructions that also define a system...

...wonder, how should registers appear in Defs be treated? Are they equal to those appearing in outs, and therefore interchangeable, or is it valid to disambiguate between them and therefore modify TableGen to only consider outs as the result of interest when processing the patterns?

The implicit defs don't participate much in the patterns. For the most part...

TableGen trace facility
A question for those of you who have developed complex TableGen files: Do you think a trace facility would be useful during debugging? The idea is to add a new statement to TableGen along these lines:
trace tag : value1, value2, ... ;
When encountered, the TableGen parser would display the tag along with the values of the specified value1, value2, etc. The tag is an identifier that makes it

Codifying our Brace rules-
I'm with Matt on this one. I much prefer the approach of ALWAYS use braces
for ifs and for loops, even if they're not needed, for basically the same
reasons as he put. The number of times I've added a statement inside an if
without braces and forget to add them is annoyingly high, especially as
it's not always an obvious error upfront. Similarly, being involved in a
