GCC 4.8.3 Released

The GNU Compiler Collection version 4.8.3 has been released. GCC 4.8.3 is the third bug-fix release containing important fixes for regressions and serious bugs in GCC 4.8.2 with over 141 bugs fixed since the previous release. This release is available from the FTP servers listed at:

gcc 4.8.3 / PR60901

PR60901 is listed in the bug fixes for gcc 4.8.3, but I don't see the patch ever applied to the 4_8 branch in the bug report, and 4.8.3 is listed as known to fail. -Kenny

Debugging LTO.

Hi, Are there any tricks I can use to debug an LTO ICE? Lto1 --help does not seem to give me an option to output trace dumps etc. What I suspect is happening is that cc1 builds erroneous LTO IR info in the objects that causes the ICEs. Is there a reader that will dump the IR from these LTO

help understanding behaviour of unsuffixed float constants

I wonder if someone could help shed light on this for me. Based on the statement in ISO C spec (ISO 9899:1990) section '6.1.3.1 Floating Constants' statement An unsuffixed floating constant has type double. it appears to me that the gcc compiler may not be in strict compliance.
