[Bug c/15495] New: Feature Request: optimization control at source level

[dbehman at ca dot ibm dot com]

When encountering application problems due to GCC optimization, often times 
the solution whether the cause of the problem is in the app's source or in GCC 
itself is to disable compilation optimization (-O0) for that particular source 
file.  This unfortunately has no granularity and results in all functions in 
that source file being compiled without optimization even if only a portion of 
one function is the location of the problem.  This feature request is for the 
ability to define (via #pragma or other) areas of source code that should not 
be optimized regardless of the command line parameters used.  I believe the 
Intel Proton/Electron compiler provides support for this.
