* these are dependencies for gcc 4 Graphite engine build. * CLooG 0.18.0 includes ISL 0.11.1 which is the backend that the build script enables. * PPL is needed by GCC build even if it isn't the chosen backend.

On the ARM, whether or not the rounding mode can be set in a way that allows
|
|
the PPL to work with floating point numbers, will depend on the actual
|
|
hardware. However, disabling the affected PPL code at run-time is
|
|
impractical. Thus, to ensure that the binary distributions of the PPL for the
|
|
ARM work as expected on any hardware, on the ARM, the affected code
|
|
is disabled at compile-time. It is still possible to build a binary
|
|
for the ARM that assumes the hardware can control the rounding mode;
|
|
for this, configure the PPL with `-DPPL_ARM_CAN_CONTROL_FPU=1' included in
|
|
CPPFLAGS.
|
|
For example:
|
|
|
|
CPPFLAGS="-DPPL_ARM_CAN_CONTROL_FPU=1" .../configure ...
