// PPC64LE ELFv2 ABI:
|
|
// - Integer args: R3-R10 (8 registers)
|
|
// - Float args: F1-F8 (8 registers)
|
|
// - Return: R3 (integer), F1 (float)
|
|
// - Stack pointer: R1
|
|
// - Link register: LR (special)
|
|
// - TOC pointer: R2 (must preserve)
|
|
|
|
// Stack layout for ELFv2 ABI (aligned to 16 bytes):
|
|
// From callee's perspective when we call BL (CTR):
|
|
// 0(R1) - back chain (our old R1)
|
|
// 8(R1) - CR save word (optional)
|
|
// 16(R1) - LR save (optional, we save it)
|
|
// 24(R1) - Reserved (compilers)
|
|
// 32(R1) - Parameter save area start (8 * 8 = 64 bytes for R3-R10)
|
|
// 96(R1) - First stack arg (a9) - this is where callee looks
|
|
// 104(R1) - Second stack arg (a10)
|
|
// 112-152 - Stack args a11-a15 (5 * 8 = 40 bytes)
|
|
// 160(R1) - TOC save (we put it here, outside param save area)
|
|
// 168(R1) - saved args pointer
|
|
// 176(R1) - padding for 16-byte alignment
