Bug ID: 83466
Summary: Wrong TLS GD sequence for ILP32
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sch...@linux-m68k.org
Target Milestone: ---
Target: aarch64-*-*
$ cat tls.c
__thread int ti;
int f (void)
{
return ti;
}
$ gcc -S -fPIC tls.c -mabi=ilp32
adrp x0, :tlsdesc:ti
ldr x1, [x0, #:tlsdesc_lo12:ti]
add x0, x0, :tlsdesc_lo12:ti
.tlsdesccall ti
blr x1
mrs x1, tpidr_el0
add x0, x1, x0
x1 + x0 needs to be performed in SImode so that it wraps around in the 32-bit
address space.
