Re: Cleanly setting C compiler options when building RTS
That's indeed one Hadrian solution. An alternative one (requires
'master' from yesterday) is:
$ hadrian/build.sh --flavour=... "stage1.rts.cc.c.opts +=
-fsanitize=address -fsanitize=undefined"
Note that I'm not quite sure who between GHC and the C compiler gets
invoked to build the RTS. If it's GHC, then you'll need to replace
'builder Cc' in Matthew's solution with 'builder (Ghc CompileCWithGhc)',
or with the key-value style approach:
$ hadrian/build.sh --flavour=... "stage1.rts.ghc.c.opts +=
-fsanitize=address -fsanitize=undefined"
You can find more about how both of those settings mechanisms work here:
https://gitlab.haskell.org/ghc/ghc/blob/master/hadrian/doc/user-settings.md
... once GitLab works again. :-)
Until then:

Hi Siddharth,
The correct way is to create a custom flavour with something like the
following in.
grts = quickFlavour { name = "grts", args = args quickFlavour <>

Hello all,
I was interested in building the GHC RTS with GCC's AddressSanitizer and Ubsan
enabled.
What I want to do very specifically is to pass "-fsanitize=address
-fsanitize=undefined" when compiling the RTS.
What's the "correct" way to set this up in the build system? Is there a
configure flag? Do I need to change the Shake script?
Thanks,

Re: Cleanly setting C compiler options when building RTS
Since you mention the Shake script, should we assume you're using Hadrian, or the Make build system?
