/* __powikf3 can be compiled 3 different ways:
|
||||||
|
|
||||||
|
1) If the assembler does not have support for the IEEE 128-bit insns
|
||||||
|
(xsaddqp, etc.) it is just compiled as __powikf2.
|
||||||
|
|
||||||
|
2) If the assembler has IEEE 128-bit floating point support, and __powikf2
|
||||||
|
is not previously defined, it is defined as __powikf2_sw.
|
||||||
|
|
||||||
|
3) If the assembler has IEEE 128-bit floating point support, and __powikf2
|
||||||
|
is included by _powikf2-hw.c, which defines __powikf2 as __powikf2_hw. The
|
||||||
|
__powikf2_hw.c is compiled with -mcpu=power9 and it automatically uses the
|
||||||
|
IEEE 128-bit instructions.
|
||||||
|
|
||||||
|
For #2/#3, float128-ifunc.c defines an ifunc function for __powikf2, that
|
||||||
|
will use the software version on power7/power8 systems, and the hardware
|
||||||
|
version on power9 systems.
|
||||||
|
|
||||||
|
The code is cloned from the code in libgcc2.c (which handles the standard
|
||||||
|
SF, DF, TF, and XF types). */
