Subject: Add a build config for bootstrapping at -Og
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8849d5034c5ab5c2e6f3fc17209504576e7c6dd4;p=gcc.git

Add a build config for bootstrapping at -Og

Although BOOT_CFLAGS can be used to bootstrap with -Og, having a
dedicated build config is sometimes more convenient.

config/
	* bootstrap-Og.mk: New file.

gcc/
	* doc/install.texi (bootstrap-Og): Document.
