2019-02-11PR libstdc++/89023 fix test that fails when <omp.h> not availableJonathan Wakely4-3/+64
Instead of a single test that only checks whether <regex> can be included in Parallel Mode, add tests for each of C++11/C++14/C++17 that check whether <bits/extc++.h> is compatible with _GLIBCXX_PARALLEL. This increases the coverage to (almost) all headers. If <omp.h> is not available then the tests will trivially pass, because we don't care about compatibility with _GLIBCXX_PARALLEL in that case.

2019-02-09[RS6000] Correct save_reg_pAlan Modra2-8/+24
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.

2019-02-08S/390: Introduce jdd constraintIlya Leoshkevich4-0/+44
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.
