Subject: [PATCH] Replace 'struct ucontext' with 'ucontext_t' type
|
|
|
|
glibc used to have:
|
|
|
|
typedef struct ucontext { ... } ucontext_t;
|
|
|
|
glibc now has:
|
|
|
|
typedef struct ucontext_t { ... } ucontext_t;
|
|
|
|
(See https://sourceware.org/bugzilla/show_bug.cgi?id=21457
|
|
for detail and rationale for the glibc change)
|
|
|
|
However, QEMU used "struct ucontext" in declarations. This is a
|
|
private name and compatibility cannot be guaranteed. Switch to
|
|
only using the standardized type name.
|
