4.37. gcc44
Updated gcc44 packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 5.
The gcc44 packages provide the GNU Compiler Collection (GCC), which includes GNU compilers and related support libraries for C, C++, and Fortran programming languages. These packages also include libgomp, the GNU implementation of the OpenMP Application Programming Interface for multi-platform shared-memory parallel programming.
Note
The gcc44 packages have been upgraded to upstream version 4.4.7, which provides a number of bug fixes and enhancements over the previous version. Among others, this update fixes bugs causing GCC internal errors when compiling code with the "-O2" and "-O3" optimization options. Also, support for the OpenMP API version 3.1 has been added to libgomp to ensure compatibility with future GCC releases. (BZ#813708)
Bug Fixes
- BZ#815207
- Previous version of gcc44 incorrectly stated that the gcc44 package includes a technical preview of GCC version 4.4. The package description has been corrected and no longer claims to provide the technical preview of GCC version 4.4.
- BZ#784360
- Due to misplaced space characters in the x86 architecture driver, the "-mxop", "-mfma4", "-mbmi" and "-mtbm" compiler options were concatenated incorrectly when compiling code with gcc44. Consequently, compilation failed with an "unrecognized command line option" error. This update fixes space characters position and the options are concatenated correctly. Code is now compiled successfully with these options.
Enhancement
- BZ#556962
- G++ previously assumed that a value of enumeration type is always in the range specified by the C++ standard. Consequently, if a program converted an arbitrary integer value to the enumeration type, the code compiled with the "-fPIC -O2" or "-fPIC -O3" options could terminate unexpectedly. With this update, the underlying code has been modified to no longer assume strict evaluation of enumeration type. The old functionality can be turned on by specifying the "fstrict-enums" option.
All users of gcc44 are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
