Bug ID: 27329
Summary: ""Node emitted out of order - late" compiling to WASM
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Backend: WebAssembly
Assignee: unassignedb...@nondot.org
Reporter: gareth_morga...@hotmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Created attachment 16209
--> https://llvm.org/bugs/attachment.cgi?id=16209&action=edit
Test case with CPP, LL and .s files (with makefile)
The attached Basic.ll file will cause this assert in LLC:
Assertion failed: I != VRBaseMap.end() && "Node emitted out of order - late",
file E:\testcode\llvm\llvm-3.8.0.src\lib\CodeGen\SelectionDAG\InstrEmitter.cpp,
line 302
Changing the argument to the Bar function to pass by value, rather than
reference makes the assert go away (Basic.works.cpp and Basic.opt.works.ll
attached).
Testcase (and makefile showing build steps) attached.
