50 check-ins occurring around 5032b5758173eebf.

2018-04-11
03:57
Move alloca to the entry blocks check-in: 7e92153b7f user: kbk tags: trunk
03:40
Eliminate stacksave/stackrestore and dynamic alloca from 'list' check-in: 11be702fa8 user: kbk tags: trunk
03:16
Rework foreachStart so that it doesn't require stacksave/stackrestore or dynamic alloca check-in: 5f0c7721ff user: kbk tags: trunk
2018-04-10
03:44
Move more alloc's into entry blocks. check-in: aa81f2ac20 user: kbk tags: trunk
03:31
Move allocas in standard library up to the entry blocks of the routines, where the inliner can find them check-in: 63a1bf25ff user: kbk tags: trunk
03:05
Reform 'buildBitArray' to use preallocated space in the LLVM callframe check-in: 7f04a0d947 user: kbk tags: trunk
02:46
Reform buildVector and clearVector to use preallocated space in the LLVM callframe check-in: a7ae4fde24 user: kbk tags: trunk
2018-04-09
02:46
Generate code for return from NRE functions and for suspend. Simplify 'clearVector' so that it can be called without the parameter specification. Next up will be to modify NRE invoke to return a tuple of {coro handle, clear flag, vector} so that NRE return can find the vector to clear it. check-in: 87e8f9147d user: kbk tags: notworking, kbk-nre
2018-04-08
21:28
Fix an error in wiring up the test for whether non-compiled commands need NRE - needed to assess 'lsort'. check-in: 978b9d80c4 user: kbk tags: notworking, kbk-nre
2018-04-06
03:29
Begin refactoring the invoke issuer in preparation for NRE.invoke. Need to fix: needsNRE and nreRequired in specializer, these need full args, not just types, in the case of builtins. Need to examine invokeExpanded because it's still used for Tcl builtins. check-in: df651f8f32 user: kbk tags: notworking, kbk-nre
2018-04-03
02:57

01:32
Fix a problem where adding and dropping references to/from FAIL IMPURE values would dereference a null pointer in the FAIL case. Closed-Leaf check-in: 0bd0c41f0a user: kbk tags: kbk-domain-check
2018-03-26
03:21
Comment out one crashing test case check-in: cbc4e47dbe user: kbk tags: kbk-domain-check, notworking
02:36

02:10
Avoid type promotion on jumpTrue and jumpFalse. check-in: 5913b29fcd user: kbk tags: kbk-domain-check, notworking
