In ISO C99/C11, the ceil, floor, round and trunc functions may or may
not raise the "inexact" exception for noninteger arguments. Under TS
18661-1:2014, the C bindings for IEEE 754-2008, these functions are
prohibited from raising "inexact", in line with the general rule that
"inexact" is only when the mathematical infinite precision result of a
function differs from the result after rounding to the target type.
GCC has no option to select TS 18661 requirements for not raising
"inexact" when expanding built-in versions of these functions inline.
Furthermore, even given such requirements, the conditions on the x86
insn patterns for these functions are unnecessarily restrictive. I'd
like to make the out-of-line glibc versions follow the TS 18661
requirements; in the cases where this slows them down (the cases using
x87 floating point), that makes it more important for inline versions
to be used when the user does not care about "inexact".
This patch fixes these issues. A new option
-fno-fp-int-builtin-inexact is added to request TS 18661 rules for
these functions; the default -ffp-int-builtin-inexact reflects that
such exceptions are allowed by C99 and C11. (The intention is that if
C2x incorporates TS 18661-1, then the default would change in C2x
mode.)
The x86 built-ins for rint (x87, SSE2 and SSE4.1) are made
unconditionally available (no longer depending on
-funsafe-math-optimizations or -fno-trapping-math); "inexact" is
correct for noninteger arguments to rint. For floor, ceil and trunc,
the x87 and SSE2 built-ins are OK if -ffp-int-builtin-inexact or
-fno-trapping-math (they may raise "inexact" for noninteger
arguments); the SSE4.1 built-ins are made to use ROUND_NO_EXC so that
they do not raise "inexact" and so are OK unconditionally.
Now, while there was no semantic reason for depending on
-funsafe-math-optimizations, the insn patterns had such a dependence
because of use of gen_truncxf<mode>2_i387_noop to truncate back to
SFmode or DFmode after using frndint in XFmode. In this case a no-op
truncation is safe because rounding to integer always produces an
exactly representable value (the same reason why IEEE semantics say it
shouldn't produce "inexact") - but of course that insn pattern isn't
safe because it would also match cases where the truncation is not in
fact a no-op. To allow frndint to be used for SFmode and DFmode
without that unsafe pattern, the relevant frndint patterns are
extended to SFmode and DFmode or new SFmode and DFmode patterns added,
so that the frndint operation can be represented in RTL as an
operation acting directly on SFmode or DFmode without the extension
and the problematic truncation.
A generic test of the new option is added, as well as x86-specific
tests, both execution tests including the generic test with different
x86 options and scan-assembler tests verifying that functions that
should be inlined with different options are indeed inlined.
I think other architectures are OK for TS 18661-1 semantics already.
Considering those defining "ceil" patterns: aarch64, arm, rs6000, s390
use instructions that do not raise "inexact"; nvptx does not support
floating-point exceptions. (This does mean the -f option in fact only
affects one architecture, but I think it should still be a -f option;
it's logically architecture-independent and is expected to be affected
by future -std options, so is similar to e.g. -fexcess-precision=,
which also does nothing on most architectures but is implied by -std
options.)
Bootstrapped with no regressions on x86_64-pc-linux-gnu. OK to
commit?

The interrupt and exception handlers are called by x86 processors. X86
hardware pushes information onto stack and calls the handler. The
requirements are
1. Both interrupt and exception handlers must use the 'IRET' instruction,
instead of the 'RET' instruction, to return from the handlers.
2. All registers are callee-saved in interrupt and exception handlers.
3. The difference between interrupt and exception handlers is the
exception handler must pop 'ERROR_CODE' off the stack before the 'IRET'
instruction.
The design goals of interrupt and exception handlers for x86 processors
are:
1. Support both 32-bit and 64-bit modes.
2. Flexible for compilers to optimize.
3. Easy to use by programmers.
To implement interrupt and exception handlers for x86 processors, a
compiler should support:
'interrupt' attribute
Use this attribute to indicate that the specified function with
mandatory arguments is an interrupt or exception handler. The compiler
generates function entry and exit sequences suitable for use in an
interrupt handler when this attribute is present. The 'IRET' instruction,
instead of the 'RET' instruction, is used to return from interrupt or
exception handlers. All registers, except for the EFLAGS register which
is restored by the 'IRET' instruction, are preserved by the compiler.
Since GCC doesn't preserve MPX, SSE, MMX nor x87 states, the GCC option,
-mgeneral-regs-only, should be used to compile interrupt and exception
handlers.
Note for compiler implementers: If the compiler generates MPX, SSE, MMX
or x87 instructions in an interrupt or exception handler, or functions
called from an interrupt or exception handler may contain MPX, SSE, MMX
or x87 instructions, the compiler must save and restore the corresponding
state.
Since the direction flag in the FLAGS register in interrupt (exception)
handlers is undetermined, cld instruction must be emitted in function
prologue if rep string instructions are used in interrupt (exception)
handler or interrupt (exception) handler isn't a leaf function.
Any interruptible-without-stack-switch code must be compiled with
-mno-red-zone since interrupt handlers can and will, because of the
hardware design, touch the red zone.
1. interrupt handler must be declared with a mandatory pointer argument:
struct interrupt_frame;
__attribute__ ((interrupt))
void
f (struct interrupt_frame *frame)
{
...
}
and user must properly define the structure the pointer pointing to.
2. exception handler:
The exception handler is very similar to the interrupt handler with
a different mandatory function signature:
typedef unsigned int uword_t __attribute__ ((mode (__word__)));
struct interrupt_frame;
__attribute__ ((interrupt))
void
f (struct interrupt_frame *frame, uword_t error_code)
{
...
}
and compiler pops the error code off stack before the 'IRET' instruction.
The exception handler should only be used for exceptions which push an
error code and all other exceptions must use the interrupt handler.
The system will crash if the wrong handler is used.
'no_caller_saved_registers' attribute
Use this attribute to indicate that the specified function has no
caller-saved registers. That is, all registers are callee-saved.
The compiler generates proper function entry and exit sequences to
save and restore any modified registers, except for the EFLAGS register.
Since GCC doesn't preserve MPX, SSE, MMX nor x87 states, the GCC option,
-mgeneral-regs-only, should be used to compile functions with
'no_caller_saved_registers'attribute.
Note for compiler implementers: If the compiler generates MPX, SSE,
MMX or x87 instructions in a function with 'no_caller_saved_registers'
attribute or functions called from a function with
'no_caller_saved_registers' attribute may contain MPX, SSE, MMX or x87
instructions, the compiler must save and restore the corresponding state.
The user can call functions specified with 'no_caller_saved_registers'
attribute from an interrupt handler without saving and restoring all
call clobbered registers.
On x86, interrupt handlers are only called by processors which push
interrupt data onto stack at the address where the normal return address
is. Interrupt handlers must access interrupt data via pointers so that
they can update interrupt data.
