[gdbarch_num_regs .. 2*gdbarch_num_regs).

range (the ABI instead of ISA registers) that comes into play when finding

64-bit addressing. On these targets, the upper 32 bits of

likely to have been sign extended to all 1s by instruction

sequences that load 32-bit addresses. For example, a typical

piece of code that loads an address is this:

But the lui sign-extends the value such that the upper 32 bits
|
|
|
|
may be all 1s. The workaround is simply to mask off these
|
|
|
|
bits. In the future, gcc may be changed to support true 64-bit

addressing, and this masking will have to be disabled. */

/* From MIPSpro N32 ABI Handbook, Document Number: 007-2816-004

|
|
|
Function results are returned in $2 (and $3 if needed), or $f0 (and $f2
|
|
|
|
if needed), as appropriate for the type. Composite results (struct,
|
|
|
|
union, or array) are returned in $2/$f0 and $3/$f2 according to the
|
|
|
|
following rules:
|
|
|
|
|
|
|
|
* A struct with only one or two floating point fields is returned in $f0
|
|
|
|
(and $f2 if necessary). This is a generalization of the Fortran COMPLEX
|
|
|
|
case.
|
|
|
|
|
|
|
|
* Any other struct or union results of at most 128 bits are returned in
|
|
|
|
$2 (first 64 bits) and $3 (remainder, if necessary).
|
|
|
|
|
|
|
|
* Larger composite results are handled by converting the function to a
|
|
|
|
procedure with an implicit first parameter, which is a pointer to an area
|
|
|
|
reserved by the caller to receive the result. [The o32-bit ABI requires
|
|
|
|
that all composite results be handled by conversion to implicit first
|
|
|
|
parameters. The MIPS/SGI Fortran implementation has always made a
|
|
|
|
specific exception to return COMPLEX results in the floating point
|
|
|
|
registers.] */

/* Floating point register management.
|
|
|
|
|
|
|
|
Background: MIPS1 & 2 fp registers are 32 bits wide. To support
|
|
|
|
64bit operations, these early MIPS cpus treat fp register pairs
|
|
|
|
(f0,f1) as a single register (d0). Later MIPS cpu's have 64 bit fp
|
|
|
|
registers and offer a compatibility mode that emulates the MIPS2 fp
|
|
|
|
model. When operating in MIPS2 fp compat mode, later cpu's split
|
|
|
|
double precision floats into two 32-bit chunks and store them in
|
|
|
|
consecutive fp regs. To display 64-bit floats stored in this
|
|
|
|
fashion, we have to combine 32 bits from f0 and 32 bits from f1.
|
|
|
|
Throw in user-configurable endianness and you have a real mess.
|
|
|
|
|
|
|
|
The way this works is:
|
|
|
|
- If we are in 32-bit mode or on a 32-bit processor, then a 64-bit
|
|
|
|
double-precision value will be split across two logical registers.
|
|
|
|
The lower-numbered logical register will hold the low-order bits,
|
|
|
|
regardless of the processor's endianness.
|
|
|
|
- If we are on a 64-bit processor, and we are looking for a
|
|
|
|
single-precision value, it will be in the low ordered bits
|
|
|
|
of a 64-bit GPR (after mfc1, for example) or a 64-bit register
|
|
|
|
save slot in memory.
|
|
|
|
- If we are in 64-bit mode, everything is straightforward.
|
|
|
|
|
|
|
|
Note that this code only deals with "live" registers at the top of the
|
|
|
|
stack. We will attempt to deal with saved registers later, when
|
|
|
|
the raw/cooked register interface is in place. (We need a general
|
|
|
|
interface that can deal with dynamic saved register sizes -- fp
|
|
|
|
regs could be 32 bits wide in one frame and 64 on the frame above
|
|
|
|
and below). */

architecture dependent, so use them to override the default sizes

|
|
|
|
comment:
|
|
|
|
|
|
|
|
``We deliberately don't allow "-gp32" to set the MIPS_32BITMODE
|
|
|
|
flag in object files because to do so would make it impossible to
|
2002-08-16 06:10:23 +02:00
|
|
|
link with libraries compiled without "-gp32". This is
|
2000-04-09 16:35:35 +02:00
|
|
|
unnecessarily restrictive.
|
2002-05-11 16:18:15 +02:00
|
|
|
|
2000-04-09 16:35:35 +02:00
|
|
|
We could solve this problem by adding "-gp32" multilibs to gcc,
|
|
|
|
but to set this flag before gcc is built with such multilibs will
|
|
|
|
break too many systems.''
|
|
|
|
|
|
|
|
But even more unhelpfully, the default linker output target for
|
|
|
|
mips64-elf is elf32-bigmips, and has EF_MIPS_32BIT_MODE set, even
|
|
|
|
for 64-bit programs - you need to change the ABI to change this,
|
2002-08-16 06:10:23 +02:00
|
|
|
and not all gcc targets support that currently. Therefore using
|
2000-04-09 16:35:35 +02:00
|
|
|
this flag to detect 32-bit mode would do the wrong thing given
|
|
|
|
the current gcc - it would make GDB treat these 64-bit programs
|
2002-08-16 06:10:23 +02:00

as 32-bit programs by default. */
