I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.

#ifndef _MATH_PRIVATE_H

/* Internally, we suppress any use of exception or rounding other
|
|
than what is supported by the hardware. This does mean that some
|
|
code will silently fail to report exceptions, set rounding mode
|
|
as expected, etc., but it allows math code to compile that otherwise
|
|
wouldn't (such as math/s_fma.c) and so is valuable.
|
|
|
|
We intentionally ignore the "exception" arguments of functions that
|
|
take an exception, since we can't even evaluate the argument
|
|
without causing a build failure. The extra level of statement
|
|
expression wrapping avoids "statement with no effect" warnings.
|
|
Since the callers don't check for errors anyway, we just claim
|
|
success in every case.
|
|
|
|
The overrides for libc_ functions must happen before we include
|
|
the generic math_private.h, and the overrides for regular
|
|
<fenv.h> functions must happen afterwards, to avoid clashing with
|
|
the declarations of those functions. */
