[cfe-dev] generate 48bits size for C int type

[gamma_chen]

Eli,

Thank your kind help. We can make int type with i48 now even though the alignment of i48 cannot set to 48 (it only can accept value is the power of 2 according we tried).

Jonathan

Is it possible to generate 48 bits size for C int type instead of the default size 32 bits? Can someone help me, please?

Properties of a target like sizeof(int) are specified in the TargetInfo class; see clang/lib/Basic/Targets.cpp .


Note that it's possible you'll run into other issues if you try to specify non-power-of-two integer types; it should work in theory, but nobody has ever tried it as far as I know.
