From: Gaosheng Cui <cuigaosheng1@huawei.com> ohos inclusion category: bugfix issue: #I3ZXZF CVE: NA ------------------------------------------------------------------------ Gcc flag '-fvisibility=hidden' specifies the visibility attribute for external linkage entities in object files. You can also selectively set visibility attributes for entities by using pairs of the #pragma GCC visibility push and #pragma GCC visibility pop compiler directives throughout your source program.when we include the hidden.h, __bss_start and __bss_end went from global symbol to local symbol,so we need to modify the regular expression to accommodate this change.
