[ARM] EABI and the default to short enums Sebastian Huber Tue Feb 14 03:00:26 2012

Hello,

the default ARM EABI configuration uses short enums by default (from "gcc/config/arm/arm.c":

/* AAPCS based ABIs use short enums by default.  */

static bool
arm_default_short_enums (void)
{
  return TARGET_AAPCS_BASED && arm_abi != ARM_ABI_AAPCS_LINUX;
}

This causes a major headache for me since some libraries assume that sizeof(any enum) > 1, e.g. the standard XDR library. Is the only possible way to disable short enums to set the ABI to ARM_ABI_AAPCS_LINUX? Which side effects does this have?

Have a nice day!
