The code depends on the extra precision offered by the long double type on x86. It's an 80-bit quantity on x86 and 64-bit on ARM, AFAICT.
Before we make changes to the code I'd like to confirm that the current tests reflect ARM Windows behavior.
It passes on windows arm (wasn't really worth attaching, oops): 0050:reader: 3624 tests executed (0 marked as todo, 0 failures), 0 skipped.
There were changes in this code, does it still fail on Wine?
reader.c now passes in wine-5.8-230-g3bb824f988. Currently bisected the fix.
writer.c still fails: austin@PrawnOS:~/wine-git/dlls/webservices/tests$ WINEDEBUG=-all make writer.ok ../../../tools/runtest -q -P wine -T ../../.. -M webservices.dll -p webservices_test.exe.so writer && touch writer.ok writer.c:371: Test failed: 2272: got 11 expected 10 writer.c:373: Test failed: 2272: got <t>:E-3</t> expected <t>1E-2</t> writer.c:371: Test failed: 2272: got 12 expected 11 writer.c:373: Test failed: 2272: got <t>-:E-3</t> expected <t>-1E-2</t> writer.c:373: Test failed: 2272: got <t>1.7976931348623156E+308</t> expected <t>1.7976931348623157E+308</t> writer.c:373: Test failed: 2272: got <t>-1.7976931348623156E+308</t> expected <t>-1.7976931348623157E+308</t> writer.c:2316: Test failed: got 00000000 writer.c:2332: Test failed: got 00000000
Filed bug 49197 for that.
