Issue: #12387
Earlier pr #13413 enabled compiling for Big-Endian target machine, but not support to compile on Big-Endian host.
Enable compilation on BE host machines by changing
-sSUPPORT_BIG_ENDIAN
command-line flag toEMCC_SUPPORT_BIG_ENDIAN
env variable. This avoids cross-cutting changes needed to propagate-sSUPPORT_BIG_ENDIAN
flag into all nestedemcc
&em++
calls.Usage:
Achieves: Emcc works on Big-Endian host and target if EMCC_SUPPORT_BIG_ENDIAN is set to 1.
Since
self.attrs
is shared across*py
scripts, no individual changes in every script are needed.
