[Qemu-devel] [PATCH] target/xtensa: Remove duplicate typedef of DisasContext

[Qemu-devel] [PATCH] target/xtensa: Remove duplicate typedef of DisasContext

[Peter Maydell]

Some older versions of gcc complain if a typedef is defined twice:

target/xtensa/translate.c:81: error: redefinition of typedef 'DisasContext'
target/xtensa/cpu.h:339: note: previous declaration of 'DisasContext' was here

Remove the now-redundant typedef from the definition of the struct in
translate.c.
