Summary: armv7l-unknown-linux-gnueabihf: valgrind error during
build of libcc1
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
I just tried a valgrind build of gcc trunk on my Raspberry PI 3B+.
It said:
echo | /home/dcb/gcc/working/./gcc/xgcc -B/home/dcb/gcc/working/./gcc/
-nostdinc -E -dM - | \
sed -n -e 's/^#define \([^_][a-zA-Z0-9_]*\).*/\1/p' \
-e 's/^#define \(_[^_A-Z][a-zA-Z0-9_]*\).*/\1/p' | \
sort -u > tmp-macro_list

Configure line is
../trunk/configure --disable-multilib \
--disable-bootstrap \
--enable-checking=valgrind \
--enable-languages=c,c++
And there is some tweeking of the top level Makefile:
sed 's;-O2;-O2 -march=native;' < Makefile > Makefile.tmp
diff Makefile Makefile.tmp
mv Makefile.tmp Makefile
