Did you try with LDC?
Just a wild guess but perhaps this triple will work:
`-mtriple=armv6k-unknown-eabi`.

I haven't yet, but I've been told also by someone else to try!
It would certainly be nice to have a true -betterC going with
this. Does LDC have equivalent flags for what devkitARM wants
passed into GCC, like:
-march=armv6k
-mtriple=armv6k-unknown-eabi
I am not sure about the "eabi".
-mtune=mpcore
This is not strictly needed. (It's an optimization parameter)
Maybe "-mcpu=mpcore" sets the optimizer to optimize for that cpu.
-mfloat-abi=hard
-float-abi=hard
-mtp=soft
Don't know if we expose this option, but LDC by default seem to
do the same as GCC's -mtp=soft:
https://d.godbolt.org/z/bmcRdI
-mword-relocations
Don't know!
-fomit-frame-pointer
This is more of a non-debug option, so not strictly needed. LDC's
option is -frame-pointer=none (for newer LDC), or
--disable-fp-elim=false (older and newer LDC).
-ffunction-sections
-function-sections
LDC is a cross compiler by nature, but you'll have to build the
runtime libraries yourself. But LDC contains an easy tool for
just that! Read:
