Identify SIIS issue before moving to z13 / z14

It is known that Assembler code using "Store into Instruction Stream" (SIIS) does not perform as well starting on z13 hardware due to a change in cache structure. It would be beneficial to have an option in the HLASM Toolkit to identify code which...

HLASM toolkit needs to support line-mode programs which use PUTGET and TGET macros

The HLASM Toolkit needs to support line-mode programs such as those which use the PUTGET and TGET macros/services. When such programs are tested using the Toolkit, the macros return invalid command buffer data. The Toolkit tests the programs as 32...

Allow the underscore separators to improve readability.

From the assembler list (ASSEMBLER-LIST Digest - 3 Jun 2012 to 4 Jun 2012 (#2012-101)) Allow underscore in values: for example allow the developer to code:A DC F'2_147_483_647' rather than A DC F'2 147 483 647' or A DC F'2147483647'

Improve how the move instruction with differing lengths is handled

There has been a lot of discussion on the assembler forum on issues with the MVC and differing length fields. Sample macros have been added that help assist in this area. Many customers have home written macros. Example statements include: 'Storag...

Identify concatenation number in SRCHFOR of sequential DSNs

When a SuperC SRCHFOR operation is performed on a concatenation of PDSes, the listing will identify a concatenation number for the data set containing the member where the string was found. But when the concatenation is of sequential data sets, th...

Reentrant check fails when labels in an RSECT are used to map dynamic (writable) storage

When using the label of a field defined in an RSECT to map some other (writable) area of storage pointed to by a register, the reentrancy check is applied. This causes message "ASMA036W" to be issued even though there is no reentrancy violation. A...

HLASM ADCON Type for Weak External Reference

HLASM would provide a new ADCON type (e.g. W or WV) that would generate an address constant containing a weak external reference to a symbol in another module to be linked with the module containing the W ADCON reference. This new ADCON type would...

System Variable Symbol &SYSRMODE

I need a way to determine the RMODE of a CSECT from within a MACRO, if the RMODE was set via either an RMODE statement, or a CATTR statement.
