--- Comment #3 from [email protected] --- there is limited support for asm() in importC to use it like pragma(mangle), added for issue 21934 this wasn't documented on the importC spec page so i only found out about it when reading the C parser source https://github.com/dlang/dmd/blob/0e3e0f9/src/dmd/cparse.d#L1845 glibc headers use asm() this way to redirect some functions based on feature macros (like whether off_t should be 64 bits on 32-bit, or whether non-standard GNU versions of some functions should be used) - if the asm() is ignored, it might silently link against the wrong function --
