enum debug_info_usage

A major contribution to object and executable size is debug information size. A major contribution to debug information size is struct descriptions replicated in several object files. The following function determines whether or not debug information should be generated for a given struct. The indirect parameter indicates that the struct is being handled indirectly, via a pointer. See opts.c for the implementation.

enum debug_struct_file

A major contribution to object and executable size is debug information size. A major contribution to debug information size is struct descriptions replicated in several object files. The following flags attempt to reduce this information. The basic idea is to not emit struct debugging information in the current compilation unit when that information will be generated by another compilation unit.

Debug information for a struct defined in the current source file should be generated in the object file. Likewise the debug information for a struct defined in a header should be generated in the object file of the corresponding source file. Both of these case are handled when the base name of the file of the struct definition matches the base name of the source file of the current compilation unit. This matching emits minimal struct debugging information.

The base file name matching rule above will fail to emit debug information for structs defined in system headers. So a second category of files includes system headers in addition to files with matching bases.

The remaining types of files are library headers and application headers. We cannot currently distinguish these two types.

enum excess_precision

The options for excess precision.

Enumerator:

EXCESS_PRECISION_DEFAULT
EXCESS_PRECISION_FAST
EXCESS_PRECISION_STANDARD

enum fp_contract_mode

Floating-point contraction mode.

Enumerator:

FP_CONTRACT_OFF
FP_CONTRACT_ON
FP_CONTRACT_FAST

enum ira_algorithm

The algorithm used for the integrated register allocator (IRA).

Enumerator:

IRA_ALGORITHM_CB
IRA_ALGORITHM_PRIORITY

enum ira_region

The regions used for the integrated register allocator (IRA).

Enumerator:

IRA_REGION_ONE
IRA_REGION_ALL
IRA_REGION_MIXED
IRA_REGION_AUTODETECT	This value means that there were no options -fira-region on the command line and that we should choose a value depending on the used -O option.

enum sanitize_code

Different instrumentation modes.

Enumerator:

SANITIZE_ADDRESS	AddressSanitizer.
SANITIZE_THREAD	ThreadSanitizer.
SANITIZE_SHIFT	UndefinedBehaviorSanitizer.
SANITIZE_DIVIDE
SANITIZE_UNREACHABLE
SANITIZE_UNDEFINED

enum stack_check_type

Type of stack check.

Enumerator:

NO_STACK_CHECK	Do not check the stack.
GENERIC_STACK_CHECK	Check the stack generically, i.e. assume no specific support from the target configuration files.
STATIC_BUILTIN_STACK_CHECK	Check the stack and rely on the target configuration files to check the static frame of functions, i.e. use the generic mechanism only for dynamic stack allocations.
FULL_BUILTIN_STACK_CHECK	Check the stack and entirely rely on the target configuration files, i.e. do not use the generic mechanism at all.

enum stack_reuse_level

The stack reuse level.

Enumerator:

SR_NONE
SR_NAMED_VARS
SR_ALL

enum symbol_visibility

Enumerator:

VISIBILITY_DEFAULT
VISIBILITY_PROTECTED
VISIBILITY_HIDDEN
VISIBILITY_INTERNAL

enum vect_cost_model

Vectorizer cost-model.

Enumerator:

VECT_COST_MODEL_UNLIMITED
VECT_COST_MODEL_CHEAP
VECT_COST_MODEL_DYNAMIC
VECT_COST_MODEL_DEFAULT

enum vtv_priority

flag_vtable_verify initialization levels.

Enumerator:

VTV_NO_PRIORITY
VTV_STANDARD_PRIORITY
VTV_PREINIT_PRIORITY

enum warn_strict_overflow_code

Names for the different levels of -Wstrict-overflow=N. The numeric values here correspond to N.

Enumerator:

WARN_STRICT_OVERFLOW_ALL	Overflow warning that should be issued with -Wall: a questionable construct that is easy to avoid even when using macros. Example: folding (x + CONSTANT > x) to 1.
WARN_STRICT_OVERFLOW_CONDITIONAL	Overflow warning about folding a comparison to a constant because of undefined signed overflow, other than cases covered by WARN_STRICT_OVERFLOW_ALL. Example: folding (abs (x) >= 0) to 1 (this is false when x == INT_MIN).
WARN_STRICT_OVERFLOW_COMPARISON	Overflow warning about changes to comparisons other than folding them to a constant. Example: folding (x + 1 > 1) to (x > 0).
WARN_STRICT_OVERFLOW_MISC	Overflow warnings not covered by the above cases. Example: folding ((x * 10) / 5) to (x * 2).
WARN_STRICT_OVERFLOW_MAGNITUDE	Overflow warnings about reducing magnitude of constants in comparison. Example: folding (x + 2 > y) to (x + 1 >= y).
