Cross-module inlining: Linker errors wrt. functions taking __FILE__ as default template parameter #1712
Description
Just tried to build sample project (dub init -t vibe.d test) with dub build -b release --compiler=ldc2 --combined and it fails. Its ok with dmd.
It's ok without combined flag and also when built without release optimisations, so I guess something with the inlining.
DUB version 1.0.0+28-geeff313, built on Aug 20 2016
It issues these flags to ldc2: -release -enable-inlining -O -w -oq
LDC the LLVM D compiler (1.1.0-beta2):
based on DMD v2.071.1 and LLVM 3.8.0
built with LDC - the LLVM D compiler (1.1.0-beta2)
Default target: x86_64-unknown-linux-gnu
Host CPU: broadwell
Fedora 24
Output:
$ dub build --combined --compiler=ldc2 -b release | ddemangle
Performing "release" build using ldc2 for x86_64.
