    • S/390: Use proper rounding mode for DFP to BFD conversions · ced8d882 
      According to IEEE 754 2008 4.3 'Rounding-direction attributes' the
rounding mode of the target format needs to be used. By not setting
the value so far we have always used the DFP rounding mode.

gcc/ChangeLog:

2018-09-12  Andreas Krebbel  <krebbel@linux.ibm.com>

	* config/s390/s390.md (PFPO_RND_MODE_DFP, PFPO_RND_MODE_BFP): New
	constants.
	("trunc<BFP:mode><DFP_ALL:mode>2")
	("trunc<DFP_ALL:mode><BFP:mode>2")
	("extend<BFP:mode><DFP_ALL:mode>2")
	("extend<DFP_ALL:mode><BFP:mode>2"): Set proper rounding mode
	according to the target operand type.

gcc/testsuite/ChangeLog:

2018-09-12  Andreas Krebbel  <krebbel@linux.ibm.com>

	* gcc.target/s390/dfp_to_bfp_rounding.c: New test.

    • [debug] Add -gdescribe-dies · 03e992ac 
      This patch adds option -gdescribe-dies.  It sets the DW_AT_description
attribute of dies that do not get a DW_AT_name attribute, to make it easier
to figure out what the die is describing.

The option exports the names of artificial variables:
...
 DIE    0: DW_TAG_variable (0x7fa934dd54b0)
+  DW_AT_description: "D.1922"
   DW_AT_type: die -> 0 (0x7fa934dd0d70)
   DW_AT_artificial: 1

...
which can be traced back to gimple dumps:
...
  char a[0:D.1922] [value-expr: *a.0];
...

Furthermore, it adds names to external references:
...
 DIE    0: DW_TAG_subprogram (0x7fa88b9650f0)
+DW_AT_description: "main"
 DW_AT_abstract_origin: die -> label: vla_1.c.6719312a + 29 (0x7fa88b965140)
...
and likewise to DW_TAG_call_site_parameter DIEs.

Bootstrapped and reg-tested on x86_64.

      	In this testcase, the call to f() can never be a constant
	expression, but that's not a problem because it isn't always
	reached by calls to g.  We were wrongly rejecting this because
	potential_constant_expression_1 lacked the jump tracking that

	version of that tracking.
