    • [RS6000] Correct save_reg_p · 9b747072 
      Fixes lack of r30 save/restore on

// -m32 -fpic -ftls-model=initial-exec
__thread char* p;
char** f1 (void) { return &p; }

and

// -m32 -fpic -msecure-plt
extern int foo (int);
int f1 (int x) { return foo (x); }

These are both caused by save_reg_p returning false when the pic
offset table reg (r30 for ABI_V4) was used, due to the logic not
exactly matching that in rs6000_emit_prologue to set up r30.

I also noticed that save_reg_p isn't following the comment regarding
calls_eh_return (since svn 267049, git 0edf78b1b2a0), and the comment
needs tweaking too.  For why the revised comment is correct, grep for
saves_all_registers in lra.c, and yes, we do want to save the pic
offset table reg for eh_return.

	PR target/88343
	* config/rs6000/rs6000.c (save_reg_p): Correct calls_eh_return
	case.  Match logic in rs6000_emit_prologue emitting pic_offset_table
	setup.

    • S/390: Introduce jdd constraint · 11719d14 
      Implementation of section anchors in S/390 back-end added in r266741
broke jump labels in S/390 Linux kernel [1].  Currently jump labels
pass global variable addresses to .quad directive in inline assembly
using "X" constraint.  In the past this used to produce regular symbol
references, however, after r266741 we sometimes get values like
(plus (reg) (const_int)), where (reg) points to a section anchor.
Strictly speaking, this is still correct, since "X" accepts anything.
Thus, now we need another way to support jump labels.

The existing "i" constraint cannot be used, since with -fPIC it must
not accept non-local symbols, however, jump labels do require that,
e.g. __tracepoint_xdp_exception from kernel proper might be referenced
from kernel modules.

The existing "ZL" constraint cannot be used for the same reason.

The existing "b" constraint cannot be used because of the way
expand_asm_stmt works.  It deduces whether the constraint allows
regs, subregs or mems, and processes asm operands differently based on
that.  "b" is supposed to accept values like (mem (symbol_ref)), and
there appears to be no way to explain to expand_asm_stmt that for "b"
mem's address must not be in a register.

This patch introduces the new machine-specific constraint named "jdd" -
"j" prefix is already used for constants, and "d" stands for "data".
It accepts anything that fits into the data section, whether or not
this might require a relocation, that is, anything that passes
CONSTANT_P check.
