- update to 3.27.0:
* VALGRIND_REPLACES_MALLOC Returns 1 if the tool replaces
malloc (e.g., memcheck). Returns 0 if the tool does not replace
malloc (e.g., cachegrind and callgrind) or if the executable is
not running under VALGRIND.
* VALGRIND_GET_TOOLNAME Get the running tool name as a
string. Takes two arguments, an input buffer pointer and the
length of that buffer. Returns the required length (including
terminating nul) for the tool name. Returns 0 and the contents
supplied buffer are not modified if not running under Valgrind.
* linux lightweight guard pages (madvise MADV_GUARD_INSTALL)
supported
* glibc 2.42+ (with linux 6.13+) uses MADV_GUARD_INSTALL to
setup stack guard pages. These lightweight guard pages are now
supported under valgrind. By default, Valgrind can handle to up to 500
madvise guard pages. With thread heavy workloads the default value
might not be sufficient. Use --max-guard-pages=N to provide a different
limit.
* If --max-guard-pages is not set explicitly, then it will
default to the --max-threads setting.
* --num-callers now has a minimum value of 2.
* x86: Support for SSE4.1 instructions has been ported from
AMD64 to (32bit) x86.
* s390x: Machine models older than z196 are no longer
supported.
* s390x: Support new z/Architecture features from the 15th
edition. In particular this enables running binaries compiled
with `-march=arch15' or `-march=z17' and exploiting the new MSA
extensions 10-13.
