| HARD_REG_SET call_clobbers_in_region | ( | unsigned int | abis, |
| const_hard_reg_set | mask, | ||
| machine_mode | mode ) |
Return the set of registers that cannot be used to hold a value of mode MODE across the calls in a region described by ABIS and MASK, where: * Bit ID of ABIS is set if the region contains a call with function_abi identifier ID. * MASK contains all the registers that are fully or partially clobbered by calls in the region. This is not quite as accurate as testing each individual call, but it's a close and conservatively-correct approximation. It's much better for some targets than just using MASK.
