* Compatibility for OCaml 4.08.1Bernhard Schommer2019-09-051-4/+4

* bswap builtins: give semantics to them, support bswap64 on all targetsBernhard Schommer2019-08-121-0/+20
| | | | | | | | | | | | * Added semantic for byte swap builtins The `__builtin_bswap`, `__builtin_bswap16`, `__builtin_bswap32`, `__builtin_bswap64` builtin function are now standard builtin functions with a defined semantics. The semantics is given in terms of the decode/encode functions used for the memory model. * Added bswap64 expansion to PowerPC 32 bits. * Added bswap64 expansion for ARM.
* Provide a float select operation for PowerPC. (#173)Bernhard Schommer2019-05-281-0/+19
| | | | | | The FP select for PowerPC stores both addresses in two subsequent stack slots and loads them using an offset created from the result of the comparison.
* Emulate the "isel" instruction on non-EREF PPC processorsXavier Leroy2019-05-201-19/+39
| | | | | On non-EREF processors it expands to instructions that destroy GPR0. Reflect this in the Asm semantics for Pisel.

* Switch conditions for eref plattforms.Bernhard Schommer2018-09-191-4/+4
| | | | | Otherwise an isel is generated if no isel is needed at all. Bug 24516
* Support __builtin_isel64 for non-EREF PPC64 platforms (#141)Xavier Leroy2018-09-181-22/+28
| | | | | | If the isel instruction is missing, it can be emulated just like we do in the 32-bit case (__builtin_isel). Follow-up to commit 51d32b92. Bug 24516
* Add builtin isel (conditional move) for int64, uint64 and _Bool (#140)Bernhard Schommer2018-09-181-1/+7
| | | | | New builtin isel variants to support conditional moves for 64bit integers and _Bool values. Bug 24516
* Generate a nop instruction after some ais annotations (#137)Bernhard Schommer2018-09-121-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | * Generate a nop instruction after ais annotations. In order to prevent the merging of ais annotations with following Labels a nop instruction is inserted, but only if the annotation is followed immediately by a label. The insertion of nop instructions is performed during the expansion of builtin and pseudo assembler instructions and is processor independent, by inserting a __builtin_nop built-in. * Add Pnop instruction to ARM, RISC-V, and x86 ARM as well as RISC-V don't have nop instructions that can be easily encoded by for example add with zero instructions. For x86 we used to use `mov X0, X0` for nop but this may not be as efficient as the true nop instruction. * Implement __builtin_nop on all supported target architectures. This builtin is not yet made available on the C side for all architectures. Bug 24067
* Fix typo in pattern match of error case, bug 24326Michael Schmidt2018-08-221-1/+1

* 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.

| | | | | | | | | | | | 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.

* | Moved expandation of debug information to Asmexpandaux.Bernhard Schommer2015-10-081-66/+5
