The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2018.05 stable Release of the Linaro GCC 7 source package.
The GCC 7 series introduced an ABI change for ARM targets by fixing a bug (present since GCC 5, see link below) that affects conformance to the procedure call standard (AAPCS). The bug affects some C++ code where class objects are passed by value to functions and could result in incorrect or inconsistent code being generated. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected by this ABI change.
For an explanation of the changes please see the following website:
This stable1 Release is based on FSF GCC 7.3.1+svn259627 and includes performance improvements and bug fixes backported from mainline GCC. This Release is based on Linaro Snapshot GCC 7.3-2018.05-rc1.
Changes in this stable GCC source package Release include:
- Updates merged from FSF GCC 7.3.1+svn259627
