Bug ID: 97365
Summary: gcvt and qgcvt do not always provide requested
precision
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
It also is confusing for the patch to perform
$(ARX) -X32_64
when immediately before the fragment created ARX by explicitly
stripping -X32_64. If it's going to perform
ar -X32_64
it should use the normal $(AR) variable.
Thanks, David

Hi,
When function splitting clones a function sinf in the host compiler, the clone

The name __deref is defined as a macro by Windows headers.
This renames the __deref() helper function to __ref. It doesn't actually
dereference an iterator. it just has the same type as the iterator's
reference type.

This solution doesn't really appeal to me, but there aren't any good options.
AIX caches shared objects in memory for faster startup. If the
archive file permissions do not include read-other (world readable),
the shared object is not cached. But using this option might cause

Dominance and reachability are two different but related things. It's trivial

Hi,
The current code assumed that super refs could be computed
indirectly, i.e. that the metadata generated by the compiler
was immutable by the runtime. This does not always hold
(it depends on the NeXT runtime version). So, compute super
refs directly.

Hi
At one time, the system linkers needed to have at least a dummy
entry for every Objective-C section in use. This removes the extra

Newer versions of ld64 are more picky about adherence to placement

Much of the existing work in the Darwin BSS and common sections

this, since it might become desirable to support section anchors for

To clarify a bit: is installed by the VC++ toolchain or WDK, not by
Windows SDK. Nevertheless, it is a system header both MS's CRT and Win32
