Simple but crude. If OPENJDK is defined then the Hotspot "alternative
source" mechanism is effectively disabled by checking for a non-
existent
path. This allows people using the alt-src mechanism to select which
type of build they want in a way that is consistent with how builds
of
OPENJDK are done in the rest of the JDK.
Tested by checking the "errorReporter.cpp" location in builds
with/without OPENJDK set, and with/without src/closed present.
This will be pushed into hotspot-rt/hotspot for hs21-b11
Hi David,
38 ifneq ($(OPENJDK),true)
39 HS_ALT_SRC_REL=src/closed
40 else
41 HS_ALT_SRC=NO_SUCH_PATH
42 endif
43 HS_COMMON_SRC=$(GAMMADIR)/$(HS_COMMON_SRC_REL)
44 HS_ALT_SRC=$(GAMMADIR)/$(HS_ALT_SRC_REL)
The 'if' block sets HS_ALT_SRC_*REL*, but the else block sets
HS_ALT_SRC (no *REL*), and that is overwritten on line 44.
I think it works because after line 44, HS_ALT_SRC == $(GAMMADIR)/,
but I doubt that was intended.
You could change line 41 to
HS_ALT_SRC_REL=$(HS_COMMON_SRC_REL)
Then when OPENJDK=true, HS_ALT_SRC==HS_COMMON_SRC, and you don't have
to rely on NO_SUCH_PATH.
I'd prefer to leave it as NO_SUCH_PATH. That way tests for the
existence of that directory (or files in those directories) will
correctly fail and won't mistakenly indicates that alt-srcs exist. I
believe there are a number of tests like that already, but I'll bet it
currently works fine (unintentionally) if HS_ALT_SRC == HS_COMMON_SRC.
