Bug ID: 28956
Summary: Name collision for RISC-V in libm ULP error table
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: manual
Assignee: unassigned at sourceware dot org
Reporter: thomas.coldrick at codethink dot co.uk
CC: mtk.manpages at gmail dot com
Target Milestone: ---
As reported in this mailing list post [0], the libm-test-ulps-name file for the
32- and 64-bit variants of RISC-V both contain "RISC-V", which means that the
generated manual can contain either the 32- or 64-bit variant with no
indication as to which it is. The differences are minor, but this could mislead
users of the documentation who are after the specific value for their
architecture.
In addition to misleading, this also has the effect of making the build of
glibc non-reproducible, as the variant selected is dependent upon the ordering
of a python os.walk() call, which varies based on the filesystem.
In the mailing list thread, it was questioned whether there's much value in
tracking both RISC-V variants separately. I lack the domain knowledge to
comment comprehensively on this (I found this bug due to build reproducibility
tests failing), but the fact that the variants differ in some mathematical
functions' error values suggests to me that there is probably at least some
value in this.
To fix this, I propose that we rename the names of the variants to "RISC-V
32-bit" and "RISC-V 64-bit" respectively in the libm-test-ulps-name files.
