MIPS: Add support for microMIPS Linux signal trampolines
The necessity for this change has been revealed in the course of
investigation related to proposed changes in the treatment of the ISA
bit encoded in function symbols on the MIPS target. This change adds
support for Linux signal trampolines encoded with the microMIPS
instruction set. Such trampolines are used by the Linux kernel if
compiled as a microMIPS binary (even if the binary run/debugged itself
contains no microMIPS code at all).
To see if we need to check whether the execution mode selected matches
the given trampoline I have checked what the bit patterns of all the
trampoline sequences decode to in the opposite instruction set. This
produced useless or at least unusual code in most cases, for example:
microMIPS/EB, o32 sigreturn, decoded as MIPS code:
30401017 andi zero,v0,0x1017
00008b7c dsll32 s1,zero,0xd
MIPS/EL, o32 sigreturn, decoded as microMIPS code:
1017 2402 addi zero,s7,9218
000c 0000 sll zero,t0,0x0
However in some corner cases reasonable code can mimic a trampoline, for
example:
MIPS/EB, n32 rt_sigreturn, decoded as microMIPS code:
2402 sll s0,s0,1
1843 0000 sb v0,0(v1)
000c 0f3c jr t0
-- here the first instruction is a 16-bit one, making things nastier
even as there are some other microMIPS instructions whose first 16-bit
halfword is 0x000c and therefore matches this whole trampoline pattern.
To overcome this problem I have decided the signal trampoline unwinder
has to ask the platform backend whether it can apply a given trampoline
pattern to the code location being concerned or not. Anticipating the
acceptance of the ISA bit proposal I decided the handler not to merely
be a predicate, but also to be able to provide an adjusted PC if
required. I decided that returning zero will mean that the trampoline
pattern is not applicable and any other value is the adjusted PC to use;
a handler may return the value requested if the trampoline pattern and
the PC requested as-is are both accepted.
This changes the semantics of the trampoline unwinder a bit in that the
zero PC now has a special value. I think this should be safe as a NULL
pointer is generally supposed to be invalid.
