My comment was more just trying to address this statement. >A lot of the things C was trying to cope with have largely died off or been relegated to incredibly niche platforms. This particular property of C is not uncommon in the embedded space. Especially since the XAP2 is by far the most used in the XAP family and is right behind ARM in volume. That said I don't know how much it is still being used by Qualcomm as I know they are now using more Xtensa cores alongside ARM. Xtensa is another major architecture sitting as small co processors in various silicon designs that is not well known, but is highly flexible. LLVM does not support even the cor versions of it. I know the Espressif team is looking to bring some support for it in.
