IBM Z: Store long doubles in vector registers when possible
On z14+, there are instructions for working with 128-bit floats (long
doubles) in vector registers. It's beneficial to use them instead of
instructions that operate on floating point register pairs, because it
allows to store 4 times more data in registers at a time, relieving
register pressure. The raw performance of the new instructions is
almost the same as that of the new ones.
Implement by storing TFmode values in vector registers on z14+. Since
not all operations are available with the new instructions, keep the
old ones available using the new FPRX2 mode, and convert between it and
TFmode when necessary (this is called "forwarder" expanders below).
Change the existing TFmode expanders to call either new- or old-style
ones depending on whether we are on z14+ or older machines
("dispatcher" expanders).

S/390: Add direct support for Linux kernel __fentry__ patching.
On i386, the difference between mcount and fentry is that fentry comes before the prolog. On s390 mcount already comes before the prolog, but takes 4 instructions. This patch introduces the more efficient implementation (just 1 instruction) and puts it under -mfentry flag. The produced code is compatible only with newer glibc versions, which provide the __fentry__ symbol and do not clobber %r0 when resolving lazily bound functions. Because 31-bit PLT stubs assume %r12 contains GOT address, which is not the case when the code runs before the prolog, -mfentry is allowed only for 64-bit code. Also, code compiled with -mfentry cannot be used for the nested C functions, since they both use %r0. In this case instrumentation is not insterted, and a new warning is issued for each affected nested function. 2018-07-16 Ilya Leoshkevich <iii@linux.ibm.com> * common.opt: Add the new warning. * config/s390/s390.c (s390_function_profiler): Emit "brasl %r0,__fentry__" when -mfentry is specified.

S/390: Disable prediction of indirect branches
This patch implements GCC support for mitigating vulnerability CVE-2017-5715 known as Spectre #2 on IBM Z. In order to disable prediction of indirect branches the implementation makes use of an IBM Z specific feature - the execute instruction. Performing an indirect branch via execute prevents the branch from being subject to dynamic branch prediction. The implementation tries to stay close to the x86 solution regarding user interface. x86 style options supported (without thunk-inline): -mindirect-branch=(keep|thunk|thunk-extern) -mfunction-return=(keep|thunk|thunk-extern) IBM Z specific options: -mindirect-branch-jump=(keep|thunk|thunk-extern|thunk-inline) -mindirect-branch-call=(keep|thunk|thunk-extern) -mfunction-return-reg=(keep|thunk|thunk-extern) -mfunction-return-mem=(keep|thunk|thunk-extern) These options allow us to enable/disable the branch conversion at a finer granularity. -mindirect-branch sets the value of -mindirect-branch-jump and -mindirect-branch-call. -mfunction-return sets the value of -mfunction-return-reg and -mfunction-return-mem. All these options are supported on GCC command line as well as function attributes. 'thunk' triggers the generation of out of line thunks (expolines) and replaces the formerly indirect branch with a direct branch to the thunk. Depending on the -march= setting two different types of thunks are generated. With -march=z10 or higher exrl (execute relative long) is being used while targeting older machines makes use of larl/ex instead. From a security perspective the exrl variant is preferable. 'thunk-extern' does the branch replacement like 'thunk' but does not emit the thunks. 'thunk-inline' is only available for indirect jumps. It should be used in environments where correct CFI is important - known as user space. Additionally the patch introduces the -mindirect-branch-table option which generates tables pointing to the locations which have been modified. This is supposed to allow reverting the changes without re-compilation in situations where it isn't required. The sections are split up into one section per option. gcc/ChangeLog: 2018-02-08 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/s390-opts.h (enum indirect_branch): Define. * config/s390/s390-protos.h (s390_return_addr_from_memory) (s390_indirect_branch_via_thunk) (s390_indirect_branch_via_inline_thunk): Add function prototypes.

S/390: New option -mpic-data-is-text-relative
For hotpatching it might be required to introduce new .text parts while keep using the existing .data/.bss sections.

S/390: Add support for arch<n> arch/tune options.
This patch adds an alternate CPU level naming following the architecture level number in the Principles of Operations manual. So instead of having z196, zEC12, and z13 you can use arch9, arch10, and arch11. The old cpu names stay valid and should preferably be used.

s390.opt ("mhard-float", [...]): Bit value inverted and documentation adjusted.
2007-03-19 Andreas Krebbel <krebbel1@de.ibm.com>
* config/s390/s390.opt ("mhard-float", "msoft-float"): Bit value
inverted and documentation adjusted.
("mhard-dfp", "msoft-dfp"): New options.
* config/s390/s390.c (s390_handle_arch_option): New architecture
switch: z9-ec.
(override_options): Sanity checks for the new options added.
* config.gcc: New architecture switch: z9-ec.
* config/s390/s390.h (processor_flags): PF_DFP added.
(TARGET_CPU_DFP, TARGET_DFP): Macro definitions added.
(TARGET_DEFAULT): Due to the s390.opt changes hard float is enabled
when the bit is NOT set so remove it from the defaults.
