Ayke van Laethem	c31aef06ba	cgo: add support for C.CString and related functions	3 years ago
Ayke van Laethem	5c0a337c4f	cgo: implement rudimentary C array decaying This is just a first step. It's not complete, but it gets some real world C code to parse. This signature, from the ESP-IDF: esp_err_t esp_wifi_get_mac(wifi_interface_t ifx, uint8_t mac[6]); Was previously converted to something like this (pseudocode): C.esp_err_t esp_wifi_get_mac(ifx C.wifi_interface_t, mac [6]uint8) But this is not correct. C array parameters will decay. The array is passed by reference instead of by value. Instead, this would be the correct signature: C.esp_err_t esp_wifi_get_mac(ifx C.wifi_interface_t, mac *uint8) So that it can be called like this (using CGo): var mac [6]byte errCode := C.esp_wifi_get_mac(C.ESP_IF_WIFI_AP, &mac[0]) This stores the result in the 6-element array mac.	3 years ago
Ayke van Laethem	1bed192de0	cgo: add support for CFLAGS in .c files This patch adds support for passing CFLAGS added in #cgo lines of the CGo preprocessing phase to the compiler when compiling C files inside packages. This is expected and convenient but didn't work before.	4 years ago
Ayke van Laethem	2e9c3a1d8d	cgo: add support for variadic functions This doesn't yet add support for actually making use of variadic functions, but at least allows (unintended) variadic functions like the following to work: void foo();	4 years ago
Ayke van Laethem	639ec1e6ee	builder: make sure -fshort-enums is used consistently The main change is in building the libraries, where -fshort-enums was passed on RISC-V while other C files weren't compiled with this setting. Note: the test already passed before this change, but it seems like a good idea to explicitly test for enum size consistency. There is also not a particular reason not to pass -fshort-enums on RISC-V. Perhaps it's better to do it there too (on baremetal targets that don't have to worry about binary compatibility).	5 years ago
Ayke van Laethem	1d7cc2c242	cgo: add support for bitfields using generated getters and setters	6 years ago
Ayke van Laethem	dfa713040a	cgo: add support for enum types Enum types are implemented as named types (with possible accompanying typedefs as type aliases). The constants inside the enums are treated as Go constants like in the Go toolchain.	6 years ago
Ayke van Laethem	2f2d62cc0c	cgo: support builtin #include headers Add support for header files bundled with the compiler by copying them into the release tarball.	6 years ago
Ayke van Laethem	b815d3f760	cgo: implement void* pointer type void* is translated to unsafe.Pointer on the Go side.	6 years ago
Ayke van Laethem	9c46ac4eed	cgo: implement char type This type is a bit more difficult because it can be signed or unsigned depending on the target platform.	6 years ago
Ayke van Laethem	d2b3a5486c	cgo: implement C unions Unions are somewhat hard to implement in Go because they are not a native type. But it is actually possible with some compiler magic. This commit inserts a special "C union" field at the start of a struct to indicate that it is a union. As such a field cannot be written directly in Go, this is a useful to distinguish structs and unions.	6 years ago
Ayke van Laethem	536086988c	cgo: implement Go arrays (constant arrays in C)	6 years ago
Ayke van Laethem	684543b7f1	cgo: implement struct types Not complete: packed structs are treated as regular structs.	6 years ago
Ayke van Laethem	da345e8723	cgo: implement bool/float/complex types	6 years ago
Ayke van Laethem	95d895646a	loader/cgo: add support for function pointers	6 years ago
Ayke van Laethem	35fb594f8f	loader/cgo: add support for pointer types	6 years ago
Ayke	01f6aff422	loader: support global variables in CGo (#173 ) Global variables (like functions) must be declared in the import "C" preamble and can then be used from Go.	6 years ago
Ayke van Laethem	6cacafb8dc	cgo: add package directory to header include paths	6 years ago
Ayke van Laethem	c6069476a7	cgo: do not rely on stdint.h to be available	6 years ago
Ayke van Laethem	0af7da9bff	cgo: add support for C.int, c.uint, etc	6 years ago
Ayke van Laethem	ecf6ffa62e	all: add bare-bones Cgo support	6 years ago
