Request for testers: GDC-5.1 Release Candidate branched

[Iain Buclaw via Digitalmars-d]

Hi,

GCC-5.1 has hit RC, and so it's all rush again to get bug fixes in
quick before the window closes.

Packages are up on Debian: https://packages.debian.org/experimental/gdc-5

Latest changes however are on github:
https://github.com/D-Programming-GDC/GDC/tree/gdc-5

Updates/Fixes from gdc-4.9 include:
- Front-end updated from 2.065.0 to 2.066.1
- Added "goto" support for GDC Extended Inline Assembler
- Added -fbounds-check=safe compiler option
- Added Runtime support for EMUTLS targets
- Added new gcc.attributes "section", "weak" and "alias"
- Partially fixed thunk support for externally referenced methods
(only variadic methods now don't work)
- Improved Closure/Frame chaining, all tests now passing in the testsuite[1]
- Improved NRVO support to take advantage of Return Slot Optimisation
(RSO), all tests now passing in the testsuite[2]

Last feature I am working on getting in is runtime exception chaining
support.  If anyone has any grand ideas, they'd be more than welcome.
