* Add new powerpc builtins.Michael Schmidt2018-04-271-0/+20
| | | | | | New builtin for 64-bit load/store with byte reversal and 64-bit mul-high. Bug 23541
* New support for inserting ais-annotations.Bernhard Schommer2017-10-191-4/+4
| | | | | | | | | | | | The ais annotations can be inserted via the new ais variants of the builtin annotation. They mainly differe in that they have an address format specifier '%addr' which will be replaced by the adress in the binary. The implementation simply prints a label for the builtin call alongside a the text of the annotation as comment and inserts the annotation together as acii string in a separate section 'ais_annotations' and replaces the usages of the address format specifiers by the address of the label of the builtin call.
* Extend builtin arguments with a pointer addition operator, continuedXavier Leroy2017-07-061-85/+148
| | | | | | | | - Add support for PowerPC, with all addressing modes. - Add support for ARM, with "reg + ofs" addressing mode. - Add support for RISC-V, with the one addressing mode. - Constprop.v: forgot to recurse in BA_addptr - volatile4 test: more tests

* Hybrid 64bit/32bit PowerPC portBernhard Schommer2017-05-031-15/+60
| | | | | | | | | | | | | This commit adds code generation for 64bit PowerPC architectures which execute 32bit applications. The main difference to the normal 32bit PowerPC port is that it uses the available 64bit instructions instead of using the runtime library functions. However pointers are still 32bit and the 32bit calling convention is used. In order to use this port the target architecture must be either in Server execution mode or if in Embedded execution mode the high order 32 bits of GPRs must be implemented in 32-bit mode. Furthermore the operating system must preserve the high order 32 bits of GPRs.

| | | | | | | | | | | | | | | | | | Also: implement __builtin_isel on non-EREF platforms with a branch-free instruction sequence. Also: extend ./configure so that it recognizes "ppc64-" and "e5500-" platforms in addition to "ppc-".
* | | Use Coq strings instead of idents to name external and builtin functions.Xavier Leroy2015-10-111-1/+1
| |/ |/| | | | | | | | | | | | | | | | | The AST.ident type represents source-level identifiers as unique positive numbers. However, the mapping identifiers <-> AST.ident differs between runs of CompCert on different source files. This is problematic when we need to produce or recognize external functions and builtin functions with fixed names, for example: * in $ARCH/Machregs.v to define the register conventions for builtin functions; * in the VST program logic from Princeton to treat thread primitives specially. So far, we used AST.ident_of_string to recover the ident associated with a string. However, this function is defined in OCaml and doesn't execute within Coq. This is a problem both for VST and for future executability of CompCert within Coq. This commit replaces "ident" by "string" in the arguments of EF_external, EF_builtin, EF_inline_asm, EF_annot, and EF_annot_val. This provides stable names for externals and builtins, as needed. For inline asm and annotations, it's a matter of taste, but using strings feels more natural. EF_debug keeps using idents, since some kinds of EF_debug annotations talk about program variables.
* | Filled in missing functions for debug information on ia32.Bernhard Schommer2015-10-091-23/+2
| | | | | | | | | | | | Like for arm and ppc the functions for section names and start and end addresses of compilation units are defined and the print_annot function is moved to Asmexpandaux.ml.
* | Filled in the rest of the funciton needed for thte debug info under arm.Bernhard Schommer2015-10-091-9/+3
| | | | | | | | | | | | The name_of_section function no returns the correct name for the debug sections, the prologue and epilogue directives are added and the labels for the live ranges are introduced in the Asmexpand pass.
* | Added versions of the tranform_* functions in AST to work with functionsBernhard Schommer2015-10-081-22/+1

* | Moved expandation of debug information to Asmexpandaux.Bernhard Schommer2015-10-081-66/+5
| | | | | | | | | | | | The function is generalized to work for all backends and takes as additional arguments functions for the printing of the simple instructions and the translation function for the arguments.
