Subject: [PATCH] lra: Avoid cycling on certain subreg reloads [PR96796]
This PR is about LRA cycling for a reload of the form:
----------------------------------------------------------------------------
Changing pseudo 196 in operand 1 of insn 103 on equiv [r105:DI*0x8+r140:DI]
Creating newreg=287, assigning class ALL_REGS to slow/invalid mem r287
Creating newreg=288, assigning class ALL_REGS to slow/invalid mem r288
103: r203:SI=r288:SI<<0x1+r196:DI#0
REG_DEAD r196:DI
Inserting slow/invalid mem reload before:
316: r287:DI=[r105:DI*0x8+r140:DI]
317: r288:SI=r287:DI#0
----------------------------------------------------------------------------
The problem is with r287. We rightly give it a broad starting class of
POINTER_AND_FP_REGS (reduced from ALL_REGS by preferred_reload_class).
However, we never make forward progress towards narrowing it down to
a specific choice of class (POINTER_REGS or FP_REGS).
I think in practice we rely on two things to narrow a reload pseudo's
class down to a specific choice:
(1) a restricted class is specified when the pseudo is created
This happens for input address reloads, where the class is taken
from the target's chosen base register class. It also happens
for simple REG reloads, where the class is taken from the chosen
alternative's constraints.
(2) uses of the reload pseudo as a direct input operand
In this case get_reload_reg tries to reuse the existing register
and narrow its class, instead of creating a new reload pseudo.
However, neither occurs here. As described above, r287 rightly
starts out with a wide choice of class, ultimately derived from
ALL_REGS, so we don't get (1). And as the comments in the PR
explain, r287 is never used as an input reload, only the subreg is,
so we don't get (2):
----------------------------------------------------------------------------
Choosing alt 13 in insn 317: (0) r (1) w {*movsi_aarch64}
Creating newreg=291, assigning class FP_REGS to r291
317: r288:SI=r291:SI
Inserting insn reload before:
320: r291:SI=r287:DI#0
----------------------------------------------------------------------------
IMO, in this case we should rely on the reload of r316 to narrow
down the class of r278. Currently we do:
----------------------------------------------------------------------------
Choosing alt 7 in insn 316: (0) r (1) m {*movdi_aarch64}
Creating newreg=289 from oldreg=287, assigning class GENERAL_REGS to r289
316: r289:DI=[r105:DI*0x8+r140:DI]
Inserting insn reload after:
318: r287:DI=r289:DI
---------------------------------------------------
i.e. we create a new pseudo register r289 and give *that* pseudo
GENERAL_REGS instead. This is because get_reload_reg only narrows
down the existing class for OP_IN and OP_INOUT, not OP_OUT.
But if we have a reload pseudo in a reload instruction and have chosen
a specific class for the reload pseudo, I think we should simply install
it for OP_OUT reloads too, if the class is a subset of the existing class.
We will need to pick such a register whatever happens (for r289 in the
example above). And as explained in the PR, doing this actually avoids
an unnecessary move via the FP registers too.
The patch is quite aggressive in that it does this for all reload
pseudos in all reload instructions. I wondered about reusing the
condition for a reload move in in_class_p:
INSN_UID (curr_insn) >= new_insn_uid_start
&& curr_insn_set != NULL
&& ((OBJECT_P (SET_SRC (curr_insn_set))
&& ! CONSTANT_P (SET_SRC (curr_insn_set)))
|| (GET_CODE (SET_SRC (curr_insn_set)) == SUBREG
&& OBJECT_P (SUBREG_REG (SET_SRC (curr_insn_set)))
&& ! CONSTANT_P (SUBREG_REG (SET_SRC (curr_insn_set)))))))
but I can't really justify that on first principles. I think we
should apply the rule consistently until we have a specific reason
for doing otherwise.

From 3d0135bf3be416bbe2531dc763d19b749eb2b856 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sanitizer: Fix asan against glibc 2.34 [PR100114]
As mentioned in the PR, SIGSTKSZ is no longer a compile time constant in
glibc 2.34 and later, so
static const uptr kAltStackSize = SIGSTKSZ * 4;
needs dynamic initialization, but is used by a function called indirectly
from .preinit_array and therefore before the variable is constructed.
This results in using 0 size instead and all asan instrumented programs
die with:
==91==ERROR: AddressSanitizer failed to allocate 0x0 (0) bytes of SetAlternateSignalStack (error code: 22)
Here is a cherry-pick from upstream to fix this.
