Detailed Description

C library Integer types (Freestanding)

This header implements the stdint.h standard header, as required by C11 S4p6. This header is specified in detail in S7.20 the same.

Actual limit values below are defined as:

• Unsigned MAXs are defined as the 0xff..ffU all-ones representation.
• Signed MINs are defined as 0x80..00 all-zeroes-but-the-last representation.
• Unsigned MAXs are defined as 0x7f..ff all-ones-but-the-last representation. These shorthands are correct for two's complement and the ones least likely to get a mistake in.

It goes without saying that this file assumes the underlying representation is two's complement and little-endian.

See https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md for the RISC-V specifics this file conforms to.
