Still ICE's in LTO, but it's not part of GDC  /  clear if it's an issue with GDC.

Tried it - ICEs are gone and it seems to work. Thanks for investigating and fixing that. Cross-language (tested C+D) inlining now works again.


Unfortunately the D inlining problems described in http://forum.dlang.org/post/mailman.75.1396605155.19942.d.gnu@puremagic.com are still present. Any chance of a fix (or workaround)?

LTO ICEs for me as of GDC 5.1.

Compiled the example from the report, output is

lto1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.archlinux.org/> for instructions.
lto-wrapper: fatal error: gdc returned 1 exit status
compilation terminated.
/usr/local/bin/ld: fatal error: lto-wrapper failed
collect2: error: ld returned 1 exit status


is this fixed?

Please raise a new issue as that is the third 🐛 in mentioned in this report.

The original was an ICE (not segv) in build_dtype, the second commit fixed an ICE in lto because common types weren't aligned, so your problem is unrelated.

(also not least because you are running a very different compiler from the
version in this report)
