Data Fields | |
| vec< gimple, va_gc > * | modified_noreturn_calls | 
| vec< tree, va_gc > * | ssa_names | 
| tree | vop | 
| struct pt_solution | escaped | 
| struct pointer_map_t * | decls_to_pointers | 
| vec< tree, va_gc > * | free_ssanames | 
| htab_t | default_defs | 
| unsigned int | ssa_renaming_needed: 1 | 
| unsigned int | rename_vops: 1 | 
| unsigned int | in_ssa_p: 1 | 
| unsigned int | ipa_pta: 1 | 
| struct ssa_operands | ssa_operands | 
| htab_t | tm_restart | 
Gimple dataflow datastructure. All publicly available fields shall have gimple_ accessor defined, all publicly modifiable fields should have gimple_set accessor.
| struct pointer_map_t* gimple_df::decls_to_pointers | 
A map of decls to artificial ssa-names that point to the partition of the decl.
| htab_t gimple_df::default_defs | 
Hashtable holding definition for symbol. If this field is not NULL, it means that the first reference to this variable in the function is a USE or a VUSE. In those cases, the SSA renamer creates an SSA name for this variable with an empty defining statement.
| struct pt_solution gimple_df::escaped | 
The PTA solution for the ESCAPED artificial variable.
| unsigned int gimple_df::in_ssa_p | 
True if the code is in ssa form.
| unsigned int gimple_df::ipa_pta | 
True if IPA points-to information was computed for this function.
A vector of all the noreturn calls passed to modify_stmt. cleanup_control_flow uses it to detect cases where a mid-block indirect call has been turned into a noreturn call. When this happens, all the instructions after the call are no longer reachable and must be deleted as dead.
| unsigned int gimple_df::rename_vops | 
True if all virtual operands need to be renamed.
| struct ssa_operands gimple_df::ssa_operands | 
| unsigned int gimple_df::ssa_renaming_needed | 
True if there are any symbols that need to be renamed.
| htab_t gimple_df::tm_restart | 
Map gimple stmt to tree label (or list of labels) for transaction restart and abort.
| tree gimple_df::vop | 
Artificial variable used for the virtual operand FUD chain.
