# General code to enable approximately all warnings. |
||||
# |
||||
# This is trivial for clang and MSVC, but GCC does not have such an option, and |
||||
# has several esoteric warnings, so we need to enable everything we want |
||||
# explicitly. We enable everything that does not require a value argument, |
||||
# except for warnings that are only relevant for very old languages (earlier |
||||
# than C99 or C++11) or non-standard extensions. |
||||
# |
||||
# Omitted common warnings: |
||||
# |
||||
# Wabi= |
||||
# Waggregate-return |
||||
# Walloc-size-larger-than=BYTES |
||||
# Walloca-larger-than=BYTES |
||||
# Wframe-larger-than=BYTES |

# Wlarger-than=BYTES |

# Wtraditional |

# Wtraditional-conversion |

# Wc90-c99-compat |

# Wdeclaration-after-statement |

# Wtraditional-conversion |
