From dc7a12bdfccd94c31f79e294f16f7549bd411b49 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 14 Apr 2019 15:51:10 -0300 Subject: docs: arm: convert docs to ReST and rename to *.rst Converts ARM the text files to ReST, preparing them to be an architecture book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

It +provides support for the exceptions bounced from VFP hardware found +on ARM926EJ-S. + +This release has been validated against the SoftFloat-2b library by +John R. Hauser using the TestFloat-2a test suite. Details of this +library and test suite can be found at: + + http://www.jhauser.us/arithmetic/SoftFloat.html + +The operations which have been tested with this package are: + + - fdiv + - fsub + - fadd + - fmul + - fcmp + - fcmpe + - fcvtd + - fcvts + - fsito + - ftosi + - fsqrt + +All the above pass softfloat tests with the following exceptions: + +- fadd/fsub shows some differences in the handling of +0 / -0 results + when input operands differ in signs. +- the handling of underflow exceptions is slightly different. If a + result underflows before rounding, but becomes a normalised number + after rounding, we do not signal an underflow exception. + +Other operations which have been tested by basic assembly-only tests +are: + + - fcpy + - fabs + - fneg + - ftoui + - ftosiz + - ftouiz + +The combination operations have not been tested: + + - fmac + - fnmac + - fmsc + - fnmsc + - fnmul -- cgit v1.2.3
