Hi, I tried to enable LTO on my port, but failed to do so. On a stupid example, I get:
$ k1-gcc -flto toto.o print.o lto1: internal compiler error: compressed stream: data error Please submit a full bug report, with preprocessed source if appropriate. See for instructions. lto-wrapper: /work1/friss/tools/open64/osprey/targia32_k1/devimage/bin/k1-gcc returned 1 exit status collect2: lto-wrapper returned 1 exit status I debugged a bit and found out that the deflate finds that the compressed data is invalid. I tried to compile with included zlib, system zlib, Fedora libelf or self-built libelf, the results are the same... Is there anything except defining TARGET_BUILTIN_DECL that targets need to do to have LTO working? Maybe our linker is somehow mangling the IR sections. Is there some way to debug those issues? Thanks, Fred
