This “fix” feels fairly hacky. The issue doesn’t occur when compiling with Clang or GCC, so it seems specific to this configuration. In my view, this behavior should be gated behind an explicit flag on the units in objdiff.json, allowing projects that need to target Armcc to opt in, while leaving the default behavior unchanged for other architectures. |

For some reason armcc always marks global symbols as hidden (referred to as
Linkageby theobjectlibrary) which makes objdiff never display any non-static functions unless the "Show hidden symbols" option is enabled, which is an undesirable workaround because that always adds a lot of noise symbols.This fixes it by never hiding any global symbols in ARM ELF objects. I don't know if this causes any collateral damage in non-armcc ecosystems but armcc only ever marks actual function symbols as global so it works.
