Errors when building with Clang #4

Open emolitor opened 3 years ago

emolitor commented 3 years ago

Annoyingly recent versions of Clang are always generating exidx which causes a link failure even when exceptions are explicitly disabled. To work around this I modified your linker script for the MCU I was testing, SAMD10, to exclude those sections [see following snippet]. Are you interested in me submitting patches like this to the mcu-starter-projects to build with Clang?

  /DISCARD/ :
  {
      // Clang always produces at least exidx so explicitly DISCARD as they are not needed
      *(.ARM.exidx);
      *(.ARM.exidx.*);
      *(.ARM.extab.*);
  }

Sure, if the patch includes adding this to all ARM linker scripts, I'll accept it.

Generally, I'm focusing on GCC, so I'm not likely to accept more esoteric things from other compilers (#pragmas and other stuff like this). But if a minor code modification can make it compile with something else - it is fine.
