Subject: PR24411, Division is not accepted in MEMORY length expression
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1c6aafe894645ca1da5c0dd0661bca19caf37ad0;p=binutils-gdb.git

PR24411, Division is not accepted in MEMORY length expression

Let's hope no one has section names starting with '/' in scripts.  If
they do, this change to fix parsing of '/' in expressiongs will break
their project.

	PR 24411
	ldlex.l (SYMBOLNAMECHAR1): Don't match '/'.
	(<EXPRESSION>"/DISCARD/"): New.
