fmerge-debug-strings

Causes the compiler to pool strings used in debugging information.

Syntax

Linux:
-fmerge-debug-strings
-fno-merge-debug-strings
macOS:
None
Windows:
None
Arguments
None
Default
-fmerge-debug-strings
The compiler will pool strings used in debugging information.
Description
This option causes the compiler to pool strings used in debugging information. The linker will automatically retain this pooling.
This option can reduce the size of debug information, but it may produce slightly slower compile and link times.
This option is only turned on by default if you are using gcc 4.3 or later, where this setting is also the default, since the generated debug tables require binutils version 2.17 or later to work reliably.
If you do not want the compiler to pool strings used in debugging information, specify option
-fno-merge-debug-strings
.
Alternate Options
None

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
