[cfe-commits] [Review] Adding a sig_atomic_t type to TargetInfo

[Ken Dyck]

The enclosed patch adds a new SigAtomicType to TargetInfo with the
intention of eventually using it to specify values for SIG_ATOMIC_MAX
and SIG_ATOMIC_MIN in clang's stdint.h. 

Currently, clang's stdint.h assumes that sig_atomic_t is a 32-bit signed
integer type on every target. This patch maintains that assumption. The
default type is 'signed int', which is 32-bits wide on all the supported
architectures except MSP430 and PIC16. On these, the default is
overridden with their 32-bit 'signed long int' type.

Reviews, comments appreciated.
