* [PATCH v2 2/3] Exclude sanitizer flags from LLVM JIT bitcode generation
@ 2026-06-12 00:15  Henson Choi <[email protected]>

From: Henson Choi @ 2026-06-12 00:15 UTC (permalink / raw)

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.

The meson build passes c_args verbatim to the clang command that emits
the JIT bitcode.  Under -fsanitize=address the instrumentation ends up
in the bitcode and breaks the JIT: any JIT-compiled query crashes the
backend with SIGILL.  The autoconf build is unaffected, as it builds
BITCODE_CFLAGS from a whitelist that never includes CFLAGS.

Filter sanitizer flags out of c_args during bitcode generation.
