The only point format that we ever support is uncompressed, which the

forecast is that point format negotiation is gone. Each curve has just
one point format and it's labeled, for historial reasons, as
"uncompressed".

MSVC and clang-cl automatically define |_WIN32| but |WIN32| is only
defined if a Windows header file has been included or if -DWIN32 was
passed on the command line. Thus, it is always better to test |_WIN32|
than |WIN32|. The convention in BoringSSL is to test |OPENSSL_WINDOWS|
instead, except for the place where |OPENSSL_WINDOWS| is defined.

Rather, take a leaf out of Chromium's book and use MSVC's __cpuid and
_xgetbv built-in, with an inline assembly emulated version for other
compilers.
This preserves the behavior of the original assembly with the following
differences:
- CPUs without cpuid aren't support. Chromium's base/cpu.cc doesn't
check, and SSE2 support is part of our baseline; the perlasm code
is always built with OPENSSL_IA32_SSE2.
- The clear_xmm block in cpu-x86-asm.pl is removed. This was used to
clear some XMM-using features if OSXSAVE was set but XCR0 reports the
OS doesn't use XSAVE to store SSE state. This wasn't present in the
x86_64 and seems wrong. Section 13.5.2 of the Intel manual, volume 1,
explicitly says SSE may still be used in this case; the OS may save
that state in FXSAVE instead. A side discussion on upstream's RT#2633
agrees.
- The old code ran some AMD CPUs through the "intel" codepath and some
went straight to "generic" after duplicating some, but not all, logic.
The AMD copy didn't clear some reserved bits and didn't query CPUID 7
for AVX2 support. This is moot since AMD CPUs today don't support
AVX2, but it seems they're expected to in the future?
- Setting bit 10 is dropped. This doesn't appear to be queried anywhere,
was 32-bit only, and seems a remnant of upstream's
14e21f863a3e3278bb8660ea9844e92e52e1f2f7.

Running make_errors.go every time a function is renamed is incredibly

Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro

ERR_print_errors, however ERR_error_string_n now uses the placeholder
"OPENSSL_internal" rather than an actual function name since that only takes
the uint32_t packed error code as input.
This updates err scripts to not emit the function string table. The
OPENSSL_PUT_ERROR invocations, for now, still include the extra

This is the first structure to be implemented with the new BIGNUM ASN.1
routines. Object reuse in the legacy d2i/i2d functions is implemented by
releasing whatever was in *out before and setting it to the
newly-allocated object. As with the new d2i_SSL_SESSION, this is a
weaker form of object reuse, but should suffice for reasonable callers.
As ECDSA_SIG is more likely to be parsed alone than as part of another
structure (and using CBB is slightly tedious), add convenient functions
which take byte arrays. For consistency with SSL_SESSION, they are named
to/from_bytes. from_bytes, unlike the CBS variant, rejects trailing
data.
Note this changes some test expectations: BER signatures now push an
error code. That they didn't do this was probably a mistake.
