From: Leif Lindholm Date: Thu, 17 Mar 2016 13:22:52 +0000 (+0800) Subject: BaseTools: use unsigned chars on ARM architectures X-Git-Tag: edk2-stable201903~7346 X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=3f7f28717892d8c82065f25070d36ba7eca3dccd BaseTools: use unsigned chars on ARM architectures By default, the ARM architectures have unsigned chars, whereas the other architectures supported by EDK2 by default have signed chars. However, EDK2 uses -funsigned-chars on those architectures to change the default behaviour. Unfortunately, the ARM architectures explicitly break their default behaviour by specifying -fsigned-chars (I presume in a pre-emptive attempt at avoiding incompatibility). Since this situation is already confusing enough, switch the ARM architectures to also specify -funsigned-chars explicitly rather than just dropping the current parameter.
