From 6862cd38a59685d15f9940fcf3882607081e3261 Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Sun, 13 Sep 2020 23:56:21 +0200 Subject: bitXXgen: add bitgen_test.c The autogenerated bitXXgen.h headers for osmo_load16le_ext() thru osmo_store64_be() are not actually tested at all. Add a test. The test output shows that the osmo_load*be_ext for a shorter len do not return nicely matching results. A practical example showing the difficulty in storing and loading 24bit integer values as/from big-endian: uint8_t buf[4]; memset(buf, 0, sizeof(buf)); osmo_store32be_ext(0x00112233, buf, 3); // stores 11 22 33 printf("%s\n", osmo_hexdump(buf, 4)); uint32_t r = osmo_load32be_ext(buf, 3); // returns 0x11223300, not 0x00112233 printf("0x%x\n", r); output is: 11 22 33 00 0x11223300 In contrast, the little-endian variant properly aligns the loaded bytes on the least significant octet: uint8_t buf[4]; memset(buf, 0, sizeof(buf)); osmo_store32le_ext(0x00112233, buf, 3); // stores 33 22 11 printf("%s\n", osmo_hexdump(buf, 4)); uint32_t r = osmo_load32le_ext(buf, 3); // returns 0x00112233 as expected printf("0x%x\n", r); output for le is: 33 22 11 00 0x112233 Change-Id:
