Bug ID: 85413
Summary: "./configure --with-build-config=bootstrap-lto " !=
"BOOT_CFLAGS +=-flto "
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/doc/install.texi;h=64ad2445a335f270200e359812bc9d2213bd2405;hb=HEAD#l2457
says:
./configure --with-build-config=bootstrap-lto is the same as adding -flto to
BOOT_CFLAGS, but providing that config/bootstrap-lto.mk contains more code than
just adding -flto, this seems not to be correct. Moreover the text in
gcc/doc/instal.texi concerning the equivalence originates from 2010, but
config/bootstrap-lto.ml was last modified in 2014. In 2010 bootstrap-lto.m4
indeed only added -flto, not it appends also =jobserver.
