[PATCH 2/2] gdb: Remove Itanium (IA-64) architecture
Tiezhu Yang
yangtiezhu@loongson.cn
Wed May 8 09:29:10 GMT 2024
The Itanium architecture is obsolete, after the upstream Linux kernel
commit cf8e8658100d ("arch: Remove Itanium (IA-64) architecture"), the
IA-64 port has been removed from the Linux kernel, so also remove the
IA-64 specific code from gdb.
Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cf8e8658100d

-
- The IA-64 architecture provides bspstore and bsp which refer
- memory locations in the RSE's backing store. bspstore is the
- next location which will be written when the RSE needs to write
- to memory. bsp is the address at which r32 in the current frame
- would be found if it were written to the backing store.
-
- The IA-64 architecture provides read-only access to bsp and
- read/write access to bspstore (but only when the RSE is in
- the enforced lazy mode). It should be noted that stores
- to bspstore also affect the value of bsp. Changing bspstore
- does not affect the number of dirty entries between bspstore
- and bsp, so changing bspstore by N words will also cause bsp
- to be changed by (roughly) N as well. (It could be N-1 or N+1
- depending upon where the NaT collection bits fall.)
-
- OTOH, the Linux kernel provides read/write access to bsp (and
- currently read/write access to bspstore as well). But it
- is definitely the case that if you change one, the other
- will change at the same time. It is more useful to gdb to
- be able to change bsp. So in order to prevent strange and
- undesirable things from happening when a dummy stack frame
- is popped (after calling an inferior function), we allow
- bspstore to be read, but not written. (Note that popping
- a (generic) dummy stack frame causes all registers that
- were previously read from the inferior process to be written
- back.) */

- break.m, break.f, and break.x), but they all have the same
- 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.
-
- SHADOW_CONTENTS has byte-based addressing (PLACED_ADDRESS and SHADOW_LEN)
- while we need bit-based addressing as the instructions length is 41 bits and
- we must not modify/corrupt the adjacent slots in the same bundle.
- Fortunately we may store larger memory incl. the adjacent bits with the
- original memory content (not the possibly already stored breakpoints there).
- We need to be careful in ia64_memory_remove_breakpoint to always restore
- only the specific bits of this instruction ignoring any adjacent stored
- bits.
-
- We use the original addressing with the low nibble in the range <0..2> which
- gets incorrectly interpreted by generic non-ia64 breakpoint_restore_shadows
- as the direct byte offset of SHADOW_CONTENTS. We store whole BUNDLE_LEN
- bytes just without these two possibly skipped bytes to not to exceed to the
- next bundle.
-
- If we would like to store the whole bundle to SHADOW_CONTENTS we would have
- to store already the base address (`address & ~0x0f') into PLACED_ADDRESS.
- In such case there is no other place where to store
- SLOTNUM (`adress & 0x0f', value in the range <0..2>). We need to know
- SLOTNUM in ia64_memory_remove_breakpoint.
-
- There is one special case where we need to be extra careful:
- L-X instructions, which are instructions that occupy 2 slots
- (The L part is always in slot 1, and the X part is always in
- slot 2). We must refuse to insert breakpoints for an address
- that points at slot 2 of a bundle where an L-X instruction is
- present, since there is logically no instruction at that address.
- However, to make things more interesting, the opcode of L-X
- instructions is located in slot 2. This means that, to insert
- a breakpoint at an address that points to slot 1, we actually
- need to write the breakpoint in slot 2! Slot 1 is actually
- the extended operand, so writing the breakpoint there would not
- have the desired effect. Another side-effect of this issue
- is that we need to make sure that the shadow contents buffer
- does save byte 15 of our instruction bundle (this is the tail
- end of slot 2, which wouldn't be saved if we were to insert
- the breakpoint in slot 1).
-
- ia64 16-byte bundle layout:
- | 5 bits | slot 0 with 41 bits | slot 1 with 41 bits | slot 2 with 41 bits |
-
- The current addressing used by the code below:
- original PC placed_address placed_size required covered
