DEC C__OpenVMS CC01057 DEC C for OpenVMS Alpha V5.7 ECO Summary
TITLE: DEC C__OpenVMS CC01057 DEC C for OpenVMS Alpha V5.7 ECO Summary
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
For OpenVMS savesets, the name of the compressed saveset
file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
saveset is copied to your system, expand the compressed
saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
For PCSI files, once the PCSI file is copied to your system,
rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
file will be the PCSI installation file which can be used to install
the ECO.

ECO KIT SUMMARY:
An ECO kit exists for DEC C V5.7 on OpenVMS Alpha V6.1 through
V7.2. This kit addresses the following problems:
o A developers command line option /switch=weak_volatile has
been enabled to specify that code generated for volatile
accesses to objects smaller than 32-bits should not use the
load-locked/store-conditional instruction sequence. In rare
kinds of code making use of direct memory-mapped I/O devices,
the locked sequences can cause hangs.
o Intrinsic functions used in combination with 64-bit pointers
could produce a number of spurious compiler diagnostics.
o The pow intrinsic erroneously produced a zero result for a
negative base value.
o /preprocessor_only output stripped the leading L character
from wide string literals.
o The expansion of the offsetof macro could trigger an assertion
failure in the compiler under the /noopt qualifier.
o The compiler sometimes generated procedure prologues that
violated the OpenVMS calling standard, leading to debugger
complaints about corrupt stack, and possible real stack
corruption in threaded code.
o The compiler generated incorrect code when casting a function
pointer to a pointer to a procedure descriptor, which was
then used to access a field in the procedure descriptor other
than the code address.
o Negative literal values in a shareable image produced by
the OpenVMS message compiler could lose sign extension when
accessed from a C programs and cast to type int.
INSTALLATION NOTES:
The system does not need to be rebooted after this kit is installed.
However, if the system is a member of a VMScluster, the other cluster
members should be rebooted or this kit should be installed on each
system in order to make use of the new image(s).
