Subject: libstdc++: Do not embed tzdata.zi for 8-bit and 16-bit targets
X-Git-Tag: basepoints/gcc-14~1570
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7314558c938245e5963494629e6436e0dccf1c8b;p=thirdparty%2Fgcc.git

libstdc++: Do not embed tzdata.zi for 8-bit and 16-bit targets

The string literal containing the static tzdata.zi information is too
large for some targets, so do not enable it by default for avr-*-* and
msp430-*-*.

libstdc++-v3/ChangeLog:

	* acinclude.m4 (GLIBCXX_ZONEINFO_DIR) [avr-*-*, msp430-*-*]: Set
	embed_zoneinfo=no
	* configure: Regenerate.
