* Extended inline asm: revised treatment of clobbered registers.Xavier Leroy2015-05-092-10/+3
| | | | | | | | | | - Treat clobbered registers as being destroyed by EF_inline_asm builtins (which is the truth, semantically). - To enable the above, represent clobbers as Coq strings rather than idents and move register_by_name from Machregsaux.ml to Machregs.v. - Side benefit: more efficient implementation of Machregsaux.name_of_register. -# Please enter the commit message for your changes.

| * | Revised semantics of comparisons between a pointer and 0.Xavier Leroy2015-03-152-3/+5
| |/ | | | | | | | | | | | | | | | | | | | | It used to be that a pointer value (Vptr) always compare unequal to the null pointer (Vint Int.zero). However, this may not be true in the final machine code when pointer addition overflows and wraps around to the bit pattern 0. This patch checks the validity of the pointer being compared with 0, and makes the comparison undefined if the pointer is out of bounds. Note: only the IA32 back-end was updated, ARM and PowerPC need updating.

| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Switch CompCert C / Clight AST of composite types (structs and unions) from a structural representation to a nominal representation, closer to concrete syntax. - This avoids algorithmic inefficiencies due to the structural representation. - Closes PR#4. - Smallstep: make small-step semantics more polymorphic in the type of the global environment. - Globalenvs: introduce Senv.t (symbol environments) as a restricted view on Genv.t (full global environments). - Events, Smallstep: use Senv instead of Genv to talk about global names.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is achieved by declaring these functions in C2C.ml, then re-checking their declarations in the global environment during the Selection pass. In passing, the "hf" parameter for SelectLong functions was removed and replaced by fixed identifiers corresponding to the actual names of the helper functions.
