Cortex-M4F Floating Point Support 120810 incremental to 1816
Hi Jifl
Here is a patch that applies fixes that we discussed past couple of days. It is
incremental to Attachment 1816.
Here are some comments. In the text below I am referencing with your numbers
from Comment #16 and Comment #17.
1) Cortex-M4/M3 selector is removed, and CYGBLD_ARCH_XFLAGS added, with comment
regarding GCC issue. Anti-flags (4) moved to CYGINT_HAL_CORTEXM_FPU and
CYGINT_HAL_FPV4_SP_D16 (respecting FPU abstraction). There is, however a
problem with unresolved conflicts when I click on CYGHWR_HAL_CORTEXM_FPU.
Funny, but it resolves when I right-click RESOLVE in conflict window.
19) Your reg_offset() code works. It would be inappropriate for me to sign it,
so I would be happy to see you in the list of contributors.
Also hal_cortex_fpu.cdl is at least 40% your ideas so we would share the
authorship.
18) I added condition to suppress FPU context saving for exceptions when not
selected ROM monitor or STUB.
I did some clean-up, formatting and banner update. Also added ChangeLog.
I did some regressions and it seems to work correctly. I will do more following
days, especially with non FPU devices (K60 and Cortex-M3).
Cheers
Ilija.
