CONFIG_COMPILER_ISA_THUMB2
¶
Compile C/C++ functions using Thumb-2 instruction set
Type: bool
Help¶
This option configures the compiler to compile all C/C++ functions using the Thumb-2 instruction set.
- N.B. The scope of this symbol is not necessarily limited to the C and
C++ languages; in fact, this symbol refers to all forms of “compiled” code.
When an additional natively-compiled language support is added in the future, this symbol shall also specify the Thumb-2 instruction set for that language.
