emscripten-fastcomp/docs/TableGen, branch 1.12.1LLVM with the emscripten fastcomp javascript backendhttps://git.amat.us/emscripten-fastcomp/atom/docs/TableGen?h=1.12.12013-03-24T19:36:51ZAllow TableGen DAG arguments to be just a name.2013-03-24T19:36:51ZJakob Stoklund Olesenstoklund@2pi.dk2013-03-24T19:36:51Zurn:sha1:4717fd4c0faf454ff37f133709320d0cfec0da89
DAG arguments can optionally be named:
(dag node, node:$name)
With this change, the node is also optional:
(dag node, node:$name, $name)
The missing node is treated as an UnsetInit, so the above is equivalent
to:
(dag node, node:$name, ?:$name)
This syntax is useful in output patterns where we currently require the
types of variables to be repeated:
def : Pat<(subc i32:$b, i32:$c), (SUBCCrr i32:$b, i32:$c)>;
This is preferable:
def : Pat<(subc i32:$b, i32:$c), (SUBCCrr $b, $c)>;

[docs] Fixup fallout from other grammar fixup.2013-02-01T03:50:20ZSean Silvasilvas@purdue.edu2013-02-01T03:50:20Zurn:sha1:f1f57c5c1a53cfcb0de23660a4d607ed57e0525a
My "excuse" for not refactoring the grammar here is to not diverge too
far from the grammar in the comments of TGParser.cpp, since I'm not
taking on the quest of majorly refactoring TGParser.cpp at the moment.
One benefit of doing this is that Ideas for refactoring and clarifying
the grammar in this document should translate almost immediately to
beneficial refactorings that can be made to TGParser.cpp.

Add an addition operator to TableGen2013-01-25T14:49:08ZHal Finkelhfinkel@anl.gov2013-01-25T14:49:08Zurn:sha1:d23a41c153712b929bd84f5e713bda5db5d6e66d
This adds an !add(a, b) operator to tablegen; this will be used
to cleanup the PPC register definitions.

TableGen/LangRef: link bang operators into the productionlist2013-01-09T02:20:31ZSean Silvasilvas@purdue.edu2013-01-09T02:20:31Zurn:sha1:96a05b3074e8633db936d6ba337a0d2bd6a7dd95
Now BangOperator should be nicely hyperlinked.

It's not just def's but actually a limited subset of Object's that are
allowed inside a multiclass.
