heard it said that the simulator uses 1 as the multiplier.

I've fixed the disassembler so that the bytes_per_line field will

be the slot multiplier. If bytes_per_line comes in as zero, it
|
|

is set to six (which is how it was set up initially). -- objdump

displays pretty disassembly dumps with this value. For our purposes,

we'll set bytes_per_line to SLOT_MULTIPLIER. This is okay since we

* ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,

(ia64_frame_cache): New struct used to cache frame info.
(ia64_register_reggroup_p): New routine used to override default
register grouping so registers without names are still saved and
restored.
(ia64_dwarf_reg_to_regnum): New routine to map gr32-gr127 to their
pseudo values.
(ia64_pseudo_register_read): New routine to read pseudo-registers.

Assume frameless until otherwise proven. Verify that the cfm for
current frame matches the cfm that should occur for the prologues
alloc insn and if equal, mark as not frameless. At end of routine,
if not frameless, calculate registers for the previous frame and store
in the cache, if a cache is provided.

encoding. (The five bit template in the low five bits of the
|
|
|
|
|
|
instruction bundle distinguishes one from another.)
|
|
|
|
|
|
|
|
|
|
|
|
The runtime architecture manual specifies that break instructions
|
|
|
|
|
|
used for debugging purposes must have the upper two bits of the 21
|
|
|
|
|
|
bit immediate set to a 0 and a 1 respectively. A breakpoint
|
|
|
|
|
|
instruction encodes the most significant bit of its 21 bit
|
|
|
|
|
|
immediate at bit 36 of the 41 bit instruction. The penultimate msb
|
|
|
|
|
|
is at bit 25 which leads to the pattern below.
|
|
|
|
|
|
|
|
|
|
|
|
Originally, I had this set up to do, e.g, a "break.i 0x80000" But
|
|
|
|
|
|
it turns out that 0x80000 was used as the syscall break in the early
|
|
|
|
|
|
simulators. So I changed the pattern slightly to do "break.i 0x080001"
|
|
|
|
|
|
instead. But that didn't work either (I later found out that this
|
|
|
|
|
|
pattern was used by the simulator that I was using.) So I ended up
|
|
|
|
|
|
using the pattern seen below. */

* ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,
bof, and nat0-nat127 as pseudo-registers.
(ia64_frame_cache): New struct used to cache frame info.
(ia64_register_reggroup_p): New routine used to override default
register grouping so registers without names are still saved and
restored.
(ia64_dwarf_reg_to_regnum): New routine to map gr32-gr127 to their
pseudo values.

Assume frameless until otherwise proven. Verify that the cfm for
current frame matches the cfm that should occur for the prologues
alloc insn and if equal, mark as not frameless. At end of routine,
if not frameless, calculate registers for the previous frame and store
in the cache, if a cache is provided.

* ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,
bof, and nat0-nat127 as pseudo-registers.
(ia64_frame_cache): New struct used to cache frame info.
(ia64_register_reggroup_p): New routine used to override default
register grouping so registers without names are still saved and
restored.

* ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,
bof, and nat0-nat127 as pseudo-registers.
(ia64_frame_cache): New struct used to cache frame info.
(ia64_register_reggroup_p): New routine used to override default
register grouping so registers without names are still saved and
restored.
(ia64_dwarf_reg_to_regnum): New routine to map gr32-gr127 to their
pseudo values.

Assume frameless until otherwise proven. Verify that the cfm for
current frame matches the cfm that should occur for the prologues
alloc insn and if equal, mark as not frameless. At end of routine,
if not frameless, calculate registers for the previous frame and store
in the cache, if a cache is provided.

* ia64-tdep.c (pseudo_regs): New enum that lists gr32-gr127, p0-p63,
bof, and nat0-nat127 as pseudo-registers.
(ia64_frame_cache): New struct used to cache frame info.
(ia64_register_reggroup_p): New routine used to override default
register grouping so registers without names are still saved and
restored.
(ia64_dwarf_reg_to_regnum): New routine to map gr32-gr127 to their
pseudo values.
(ia64_pseudo_register_read): New routine to read pseudo-registers.
(ia64_pseudo_register_write): New routine to write pseudo-registers.
(ia64_alloc_frame_cache): New routine to create a new
ia64_frame_cache.
(examine_prologue): Change prototype to add next_frame pointer.
Assume frameless until otherwise proven. Verify that the cfm for
current frame matches the cfm that should occur for the prologues
alloc insn and if equal, mark as not frameless. At end of routine,
if not frameless, calculate registers for the previous frame and store
in the cache, if a cache is provided.
(ia64_skip_prologue): Use new prototype when calling examine_prologue
and pass 0 for next_frame.
(ia64_store_return_value): Change to use convert_typed_floating()
instead of calling ia64_convert_to_raw().
(ia64_extract_return_value): Change to use convert_typed_floating()
instead of calling ia64_convert_to_virtual().
