I am wondering if anyone has done any tests using LTO in SPL? For those of us with limited resources, I noticed that we're creeping up in size, especially when using DM in SPL.
I made a few attempts to enable -flto during compile, but the .S files fail to assemble. I found some references that indicating not to use -flto when running the assembler, but we appear to be using CFLAGS for assembly and I am not entirely sure how to apply -fno-lto to just the assembly files.
I am focusing on ARMv7 right now, but if anyone has any suggestions or have started something, on a different architecture, I'd like to experiment a little. I am not sure if the LTO will buy us much anyway, but any little improvement during SPL would be appreciated.
thanks
