ACPICA: Introduce ACPI_NONSTRING

2025-05-12T13:38:42Z

ACPICA commit 878823ca20f1987cba0c9d4c1056be0d117ea4fe In order to distinguish character arrays from C Strings (i.e. strings with a terminating NUL character), add support for the "nonstring" attribute provided by GCC. (A better name might be "ACPI_NONCSTRING", but that's the attribute name, so stick to the existing naming convention.) GCC 15's -Wunterminated-string-initialization will warn about truncation of the NUL byte for string initializers unless the destination is marked with "nonstring". Prepare for applying this attribute to the project. Link: https://github.com/acpica/acpica/commit/878823ca Signed-off-by: Rafael J.

ACPICA: Introduce ACPI_FLEX_ARRAY

2023-04-06T18:29:12Z

ACPICA commit e73b227e8e475c20cc394f237ea35d592fdf9ec3 In order to enable using -fstrict-flex-arrays with GCC and Clang in the Linux kernel, each trailing dynamically sized array must be defined as proper C99 "flexible array members" (FAM). Unfortunately, ACPICA has a bunch of technical debt, dating back to before even the GNU extension of 0-length arrays, meaning the code base has many 1-element and 0-length arrays defined at the end of structures that should actually be FAMs. One limitation of the C99 FAM specification is the accidental requirement that they cannot be in unions or alone in structs. There is no real-world reason for this, though, and, actually, the existing GNU extension permits this for 0-length arrays (which get treated as FAMs). Add the ACPI_FLEX_ARRAY() helper macro to work around this requirement so that FAMs can be defined in unions or alone in structs. Since this behavior still depends on GNU extensions, keep the macro specific to GCC (and Clang) builds. In this way, MSVC will continue to use 0-length arrays (since it does not support the union work-around). When MSVC grows support for this in the future, the macro can be updated.

ACPI: Drop ACPI_USE_BUILTIN_STDARG ifdef from acgcc.h

2021-11-05T14:51:13Z

The ACPI_USE_BUILTIN_STDARG symbol is never set in the kernel build, so stop checking it in include/acpi/platform/acgcc.h and drop all of the macros depending on it (which appear to duplicate the analogous macros from linux/stdarg.h, but in fact are never used).
