[cfe-users] Reproducible builds

[Stephan Gatzka via cfe-users]

Well,

that's not exactly what I meant. In gcc, if you use -flto a c file 
compiled twice leads to different binaries, if you don't add 
-frandom-seed=<something>.

clang also supports the switch -frandom-seed=<something>, but the object 
files produced by clang are always binary equal.

Meanwhile I think clang intorduced -frandom-seed only for gcc compatibility:

But thanks for the hint. :)
