- Subject: Usage of -Os in 5.4 causing issues

I noticed that at least on my platform, using Lua 5.4 makes valgrind output practically unusable, with lots of messages like https://gist.github.com/q66/dacbbec6eefc3e7a17e4d95d7f4343f8 (with 5.3: https://gist.github.com/q66/71b1eda9f9d07cffb920459f9ae1db3c)
I went to investigate and turns out it's 5.4's new usage of -Os to compile llex.c/lparser.c/lcode.c; setting CMCFLAGS to empty results in the output being as clean as it's ever been. This is on powerpc64le/Linux/gcc 9.3.
Regards,
Daniel
