Re: The test suite for libosmocore fails on big-endian architectures

this works for me, but I still don't understand why, the ordering of bitfields looks quite strange to me :)

The reversal needs to be done byte-wise. So in this example:

...

+#if OSMO_IS_LITTLE_ENDIAN == 1 uint8_t code_hi:6; uint8_t gs:2; uint8_t update:4; uint8_t code_lo:4;

The first byte is code_hi and gs, reverse those:

...

+#else

• uint8_t gs:2;
• uint8_t code_hi:6;

Next byte is update and code_lo, reversed:

...

• uint8_t code_lo:4;
• uint8_t update:4;

+#endif

I hope that helps :)

• uint8_t gs:2;

• uint8_t code_hi:4;
• uint8_t code_lo:4;
