gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.
This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.
EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.

As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.
test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.
Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

When no SSE (fxsave) context is available but x87 (fsave) context is, use the
x87 context.
This also embeds the x87 FPU opcode from the fxsave fop field in bits 16-26 of
the fsave error_selector field, true to the layout of the fsave structure. See
Intel SDM volume 1 (253665-061) 8.1.10 and figure 8-9.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

and its test.
Minidump context structures now interoperate more easily with snapshot
CPUContext structures, while maintaining identical layout to before.
This is facilitated by reusing the Fxsave types for the substructures
which were completely identical, and by using compatible logic to
initialize the minidump and snapshot structures for testing.
