From f79a9c775ff0a59027f274a237d98b5f8d31c022 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 7 Feb 2023 21:45:23 +0100 Subject: [PATCH] package/wolfssl: handle ARM Thumb situation By default on ARM32, wolfssl uses assembly instructions that are not supported on Thumb (original Thumb, not Thumb 2), causing a build failure: /tmp/ccgn33X7.s:299: Error: selected processor does not support `umlal r4,r5,r10,ip' in Thumb mode /tmp/ccgn33X7.s:386: Error: instruction not supported in Thumb16 mode -- `adds r4,r4,r6' /tmp/ccgn33X7.s:387: Error: unshifted register required -- `adc r3,r3,#0' /tmp/ccgn33X7.s:395: Error: instruction not supported in Thumb16 mode -- `adds r4,r4,r6' Fix that by passing --with-arm-target=thumb, which tells wolfssl to use a different set of assembly routines.
