Macro Definition Documentation
◆ __has_attribute
| #define __has_attribute | ( | x | ) | 0 |
This header file contains macro definitions to support portability. This header is shared between C and ASM code, so it MUST only contain macro definitions. It MUST not contain any C code.
This header ONLY defines macros to detect platforms/feature support.

◆ __has_builtin

◆ __has_feature
| #define __has_feature | ( | x | ) | 0 |

◆ DYNAMIC_BMI2
| #define DYNAMIC_BMI2 0 |

◆ ZSTD_ADDRESS_SANITIZER
| #define ZSTD_ADDRESS_SANITIZER 0 |
Definition at line 55 of file portability_macros.h.
◆ ZSTD_ASM_SUPPORTED
| #define ZSTD_ASM_SUPPORTED 0 |
Only enable assembly for GNUC compatible compilers, because other platforms may not support GAS assembly syntax.
Only enable assembly for Linux / MacOS, other platforms may work, but they haven't been tested. This could likely be extended to BSD systems.
Disable assembly when MSAN is enabled, because MSAN requires 100% of code to be instrumented to work.

◆ ZSTD_ENABLE_ASM_X86_64_BMI2
| #define ZSTD_ENABLE_ASM_X86_64_BMI2 0 |
Determines whether we should enable assembly for x86-64 with BMI2.
Enable if all of the following conditions hold:
- ASM hasn't been explicitly disabled by defining ZSTD_DISABLE_ASM
- Assembly is supported
- We are compiling for x86-64 and either:
- DYNAMIC_BMI2 is enabled
- BMI2 is supported at compile time
