Use this panel to specify processor behavior. You can specify the file paths and define macros.
The following figure shows the Processor panel.
The following table lists and defines each option of the Processor panel.
| Option | Description |
|---|---|
| Allow Semihosting | This flag defines the built-in macro, __SEMIHOSTING. This allows users to access ARM semihosting features in their application (such as console output). NOTE: The "hosted"-type runtime libraries are built with -semihosting. |
| Enable ARM Shared Library Architecture Support | Equivalent to -ashla, this flag is not active for this product. |
| Pool Constants and Disable Dead-Stripping | Equivalent to -constpool, this flag will combine the literal constant pools of multiple functions in a translation unit. The implication of this is that multiple functions will reside in a single ELF section, thus disabling dead-stripping by the linker (each function must reside in a unique ELF section to be dead-stripped). |
| Generate Code for Profiling | Equivalent to -profile, this flag instruments the prologue and epilogue of functions to collect profiling data. |
| Position-Independent Code | Check to generate position independent code (PIC) that is non relocatable. |
| Position-Independent Data | Check to generate non-relocatable position-independent data (PID). PID is available with 16- and 32-bit addressing. |
| Place Read-Only Strings in .rodata Section | Equivalent to -readonlystring or -rostr, this flag places constant string data in .rodata ELF sections. |
| Use Generic Static Symbol Names | Equivalent to -generic_symbol_names, Obfuscates the names of static symbols within binaries (such as libraries) as protective measure against unauthorized persons disassembling the binary. Such a disassembly can reveal the names of static symbols and may expose internal structures and other proprietary details.The compiler replaces static symbol names with generic ones, for example "my_local" becomes "@1234". This feature only works when debugging is disabled. |
| Set Max Size before Spill to .sdata (bytes) | Equivalent to -sdatathreshold, the Small Data text box specifies the largest size, in bytes, of items that the linker stores in small data address space ( .sdata and .sbss). For example, a value 16 in this box means that the linker will store all non-constant data items of 16 or fewer bytes in this space. The size value specifies the maximum size, in bytes, of all objects in the small data section (typically named " .sdata"). The linker places objects that are greater than this size in the data section (typically named " .data") instead. The default value for size is 8. This is a both a linker and compiler option. |
