| * Add op for float max and min for x86.Bernhard Schommer2022-02-0710-23/+66
| | | | | | | | | | | | | | | | | | | | The ops `Omaxf` and `Ominf` have the same semantics as `minsd` and `maxsd` instruction, i.e. if both arguments are equal the second argument is returned as well as for NaN. The operations are the used in SelectOp to implement the built-in function `__builtin_fmax` and `__builtin_fmin`. Bug 32640
| * Return second arg for float min/max on x86.Bernhard Schommer2022-02-071-4/+4
| | | | | | | | | | | | If both arguments are zero the second argument is returned independ from their sign. Bug 32640

| * Protect against overflows in `leaq` (all forms)Bernhard Schommer2021-08-271-22/+27
| | | | | | | | | | | | | | | | leaq's offsets can overflow (not fit in 32 bits) in other cases than those fixed in 4daebb7a0, e.g. in the expansion of __builtin_memcpy_aligned. This commit implements full normalization of the `leaq` instructions produced in Asmexpand, following the same method used in Asmgen.
| * Protect against overflows in `leaq N(src), dst` (#407)Xavier Leroy2021-08-271-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | If N does not fit in signed 32 bits, `leaq` cannot be used and `mov; addq` must be used instead. This was already the case for `leaq` instructions produced by the Asmgen pass, but not for some `leaq` instructions produced by Asmexpand. Normally, assemblers should fail if the `leaq` offset is not representable, but this is not always the case (see issue #406). Fixes: #406

| | | | | | | | | | | | | | | | | | As reported in #399, it seems better to use `##` instead of `#` as comment delimiter under macOS. For the time being we keep using `#` for Linux and Cygwin. Closes: #399

| * Section handling: finer control of variable initializationXavier Leroy2021-02-231-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Distinguish between: - uninitialized variables, which can go in COMM if supported - variables initialized with fixed, numeric quantities, which can go in a readonly section if "const" - variables initialized with symbol addresses which may need relocation, which cannot go in a readonly section even if "const", but can go in a special "const_data" section. Also: on macOS, use ".const" instead of ".literal8" for literals, as not all literals have size 8.
| * Introduce and use PrintAsmaux.variable_sectionXavier Leroy2021-02-231-6/+6
| | | | | | | | | | | | | | This is a generalization of the previous PrintAsmaux.common_section function that - handles initialized variables in addition to uninitialized variables; - can be used for Section_const, not just for Section_data.
| * Qualify `Hint` as `Global Hint` where appropriateXavier Leroy2021-01-211-1/+1
| | | | | | | | | | | | | | This avoids a new warning of Coq 8.13. Eventually these `Global Hint` should become `#[export] Hint`, with a cleaner but different meaning than `Global Hint`.
| * "macosx" is now called "macos"Xavier Leroy2021-01-182-2/+2
| | | | | | | | | | The configure script still accepts "macosx" for backward compatibility, but every other part of CompCert now uses "macos".
| * Support re-normalization of function parameters at function entryXavier Leroy2021-01-161-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is complementary to 28f235806 Some ABIs leave more flexibility concerning function parameters than CompCert expects. For instance, the AArch64/ELF ABI allow the caller of a function to leave unspecified the "padding bits" of function parameters. As an example, a parameter of type "unsigned char" may not have zeros in bits 8 to 63, but may have any bits there. When the caller is compiled by CompCert, it normalizes argument values to the parameter types before the call, so padding bits are always correct w.r.t. the type of the argument. This is no longer guaranteed in interoperability scenarios, when the caller is not compiled by CompCert. This commit adds a general mechanism to insert "re-normalization" conversions on the parameters of a function, at function entry. This is controlled by the platform-dependent function Convention1.return_value_needs_normalization. The semantic preservation proof is still conducted against the CompCert model, where the argument values of functions are already normalized. What the proof shows is that the extra conversions have no effect in this case. In future work we could relax the CompCert model, allowing functions to pass arguments that are not normalized.
| * Replace `omega` tactic with `lia`Xavier Leroy2020-12-297-60/+60
| | | | | | | | | | | | | | | | | | | | | | Since Coq 8.12, `omega` is flagged as deprecated and scheduled for removal. Also replace CompCert's homemade tactics `omegaContradiction`, `xomega`, and `xomegaContradiction` with `lia` and `extlia`. Turn back on the deprecation warning for uses of `omega`. Make the proof of `Ctypes.sizeof_pos` more robust to variations in `lia`.
| * Changed cc_varargs to an option typeBernhard Schommer2020-12-251-2/+2
| | | | | | | | | | | | Instead of being a simple boolean we now use an option type to record the number of fixed (non-vararg) arguments. Hence, `None` means not vararg, and `Some n` means `n` fixed arguments followed with varargs.
