276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	23
336 3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	24 There are two main ABIs in use for MIPS64 chips, \emph{N64}\cite{MIPSn32/n64}
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	25 and \emph{N32}\cite{MIPSn32/n64}. Both are basically the same, except that N32
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	26 uses ILP32 as programming model (32-bit pointers and long integers), whereas
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	27 N64 uses LP64 (64-bit pointers and long integers). All registers of a MIPS64
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	28 chip are considered to be 64-bit wide, even for the N32 calling convention.\\
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	29 The word size is defined to be 32 bits, a dword 64 bits. Note that this is due
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	30 to historical reasons (terminology didn't change from MIPS32).\\
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	31 Other than that there are correspoding 64-bit versions other MIPS32 ABIs, e.g.
3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	32 the EABI\cite{MIPSeabi} and O64\cite{MIPSo64}.

276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	36 For MIPS 64-bit machines, dyncall supports the N64 calling conventions for calls and callbacks (for all four combinations of big/little-endian, and soft/hard-float targets).
276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	37 The N32 calling convention might work - it used to, but hasn't been tested, recently.

276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	76 \item for hard-float targets: register arguments are passed via \$a0-\$a7 for integers and \$f12-\$f19 for floats - with mixed float and int parameters, some registers are left out (e.g. first parameter ends up in \$a0 or \$f12, second in \$a1 or \$f13, etc.)

276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	83 \item if the callee takes the address of one of the parameters and uses it to address other unnamed parameters (e.g. varargs) it has to copy - in its prolog - the the argument registers to a reserved stack area adjacent to the other parameters on the stack (only the unnamed integer parameters require saving, though) % @@@ seems to ONLY spill with varargs, never for any other reason
276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	84 \item float arguments passed in the variable part of a vararg call are passed like integers, meaning float registers don't ever need to be saved that way, so only \$a0-\$a7 are need to be spilled
276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	85 \item quad precision float arguments are passed in even-odd register pairs, skipping one register if needed
276eb8c87aa0 - review and fixes, cleanup, amendments to calling convention appendix of manual Tassilo Philipp parents: 305 diff changeset	86 \item integer parameters \textless\ 64 bit are right-justified (meaning occupy higher-address bytes) in their 8-byte slot on the stack, requiring extra-care for big-endian targets
336 3c6bc720bc1f - doc: added mips64/n32 stub Tassilo Philipp parents: 328 diff changeset	87 \item single precision float parameters (32 bit) are left-justified in their 8-byte slot on the stack, but are right justified in fp-registers on big endian targets, as they aren't promoted (actually, official docs says "undecided", but real world implementations seem to use what is described here)
