tools/compiler: match glibc 2.42 definition of __attribute_const__

2026-07-05T23:24:20+00:00

glibc 2.42 added __attribute_const__ to sys/cdefs.h: # define __attribute_const__ __attribute__ ((__const__)) GCC 15 warns when a macro is redefined to a different replacement list (-Wbuiltin-macro-redefined). Since host tool Makefiles (resolve_btfids, objtool) pass -Werror, this conflict becomes fatal. The warning is suppressed on standard native builds because GCC treats /usr/include as a system header path (-isystem), and macro-redefinition warnings from system headers are silently suppressed by GCC. It fires when glibc headers are on a regular include path (-I) instead, which is the case in cross-compilation setups such as NixOS, where the sysroot's glibc is passed explicitly via -I rather than -isystem. Per (C11 6.10.3), identical replacement lists are accepted silently. Match the glibc definition exactly, including the space before "((", so the redefinition is accepted without warning regardless of whether glibc headers are treated as system or non-system includes.

tools/nolibc: mark arg1 operand in __nolibc_syscall0() as write-only

2026-07-03T18:00:09+00:00

__nolibc_syscall0() does not set the arg1 variable before passing it to the asm block. This uninitialized variable read is undefined behavior. Clang can miscompile this. Mark the asm operand as write-only to fix this.

bitmap: Replace ASSEMBLY with ASSEMBLER in header files

2026-07-03T16:44:17+00:00

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__ macro that is provided by the compilers. This is a completely mechanical patch (done with a simple "sed -i" statement).

tools/nolibc: unistd: Add readlink()

Add readlink(). This is needed to test getcwd(). Signed-off-by: Daniel Palmer Acked-by: Willy Tarreau Link: https://patch.msgid.link/20260702085101.3304547-3-daniel@thingy.jp Signed-off-by: Thomas Weißschuh

tools/nolibc: unistd: Add getcwd()

2026-07-03T06:07:59+00:00

Add getcwd() for getting the current working directory. The behaviour matches what musl is doing except for one important difference: If the passed buf is NULL musl (and glibc) uses a big buffer on the stack and that is then strdup()'d and returned. According to the man page for getcwd() this is a glibc extension and I don't think we need it in nolibc.

tools/include: include stdint.h for SIZE_MAX in overflow.h

2026-07-02T02:02:56+00:00

tools/include/linux/overflow.h uses SIZE_MAX in its size helper functions. Include stdint.h so tools users that include overflow.h without another SIZE_MAX provider can build.
