Subject: [PATCH] Fix hardfloat detection
|
||||
|
||||
based on the same patch for nodejs which says :
|
||||
|
||||
gcc has a builtin define to denote hard abi when in use, e.g. when
|
||||
using -mfloat-abi=hard it will define __ARM_PCS_VFP to 1 and therefore
|
||||
we should check that to determine which calling convention is in use
|
||||
and not __VFP_FP__ which merely indicates presence of VFP unit
|
||||
|
||||
The fix has been provided by Khem Raj <raj.khem@gmail.com>
