Hi
While compiling RTEMS for the STM32F4 we discovered a bug in the recent patch
for the FPv4-SP support. I don't feel familiar enough with the code to fix it
so filling in a bug report.
The bug resides in the armv7m-context-switch.c line 59 and is related to a
missing #ifdef protection for the ARM_CONTEXT_CONTROL_D8_OFFSET I guess.

Reverting tha commit helps for the build process but the support is not there.

commit id: 8ae373235b316ff10c3b6f30ac1f2efed9bec011

Best regards
Tomasz Gregorek
