Attachment: fix nsVoidArray

does this fix your build?

Comment 2

[[e-mail]]

note, dbaron has a patch in bug 409384 that should also fix this for nsVoidArray.

Comment 3

[Dennis Gilmore]

it does not fix it for me.  I am building with gcc-4.3  build logs can be found http://sparc.koji.fedoraproject.org/koji/taskinfo?taskID=51185

ok, i'm going to take another stab at a fix (for real, this time!).

in the meantime, this isn't a cookie bug, -> core/xpcom

Comment 5

Attachment: v2

turn off -Wcast-align on sparc. let it join ia64 in its uniqueness.

Comment 6

[[e-mail]]

(i tried fixing nsTHashtable, but it's not possible - we know the casts are correct but there's no way of telling the compiler so, short of sprinkling __align() constructs. other option is to disable WARNINGS_AS_ERRORS for cookies on sparc, but this is a pretty pervasive warning and sparc is a long shot from tier 1.)

Patch Fixing for sparc64 

Could you just change this to a case statement at this point? It's starting to get ugly.

rewritten patch using case statement

>+    case "$CPU_ARCH" in

looks like you've got your sense mixed up... you want the _WARNINGS_CFLAGS bit to be in the * case, no? ;)

Comment 18

[Dennis Gilmore]

Attachment: Really update to use case statement

you were right.  I was still building with the patch appalied.  the new one is better

Comment 19

[Dennis Gilmore]

it builds on sparc32 with the patch applied.  testing sparc64 now.

Comment 20

[Dennis Gilmore]

Attachment: make sparc same as ppc

The patch doesnt apply to current cvs checkouts due to adding to the if statement to handle the intel compiler. i refactored handing of sparc cpus to be the same as powerpc.  ive built on sparc64 with the new patch applied.
