-
- TCG variables are the inputs and outputs of TCG ops, as described
- in tcg/README. Target CPU front-end code uses these types to deal
- with TCG variables as it emits TCG code via the tcg_gen_* functions.
- They come in several flavours:
- * TCGv_i32 : 32 bit integer type
- * TCGv_i64 : 64 bit integer type
- * TCGv_ptr : a host pointer type
- * TCGv_vec : a host vector type; the exact size is not exposed
- to the CPU front-end code.
- * TCGv : an integer type the same size as target_ulong
- (an alias for either TCGv_i32 or TCGv_i64)
- The compiler's type checking will complain if you mix them
- up and pass the wrong sized TCGv to a function.
-
- Users of tcg_gen_* don't need to know about any of the internal
- details of these, and should treat them as opaque types.
- You won't be able to look inside them in a debugger either.
-
- Internal implementation details follow:
-
- Note that there is no definition of the structs TCGv_i32_d etc anywhere.
- This is deliberate, because the values we store in variables of type
- TCGv_i32 are not really pointers-to-structures. They're just small
- integers, but keeping them in pointer types like this means that the
- compiler will complain if you accidentally pass a TCGv_i32 to a
- function which takes a TCGv_i64, and so on. Only the internals of
- TCG need to care about the actual contents of the types. */

- * Where translation blocks have been linked, execution
- * may proceed from the given TB into successive ones.
- * Control eventually returns only when some action is needed
- * from the top-level loop: either control must pass to a TB
- * which has not yet been directly linked, or an asynchronous
- * event such as an interrupt needs handling.
- *
- * Return: The return value is the value passed to the corresponding
- * tcg_gen_exit_tb() at translation time of the last TB attempted to execute.
- * The value is either zero or a 4-byte aligned pointer to that TB combined
- * with additional information in its two least significant bits. The
- * additional information is encoded as follows:
- * 0, 1: the link between this TB and the next is via the specified
- * TB index (0 or 1). That is, we left the TB via (the equivalent
- * of) "goto_tb <index>". The main loop uses this to determine
- * how to link the TB just executed to the next.
- * 2: we are using instruction counting code generation, and we
- * did not start executing this TB because the instruction counter
- * would hit zero midway through it. In this case the pointer
- * returned is the TB we were about to execute, and the caller must
- * arrange to execute the remaining count of instructions.
- * 3: we stopped because the CPU's exit_request flag was set
- * (usually meaning that there is an interrupt that needs to be
- * handled). The pointer returned is the TB we were about to execute
- * when we noticed the pending exit request.
- *
- * If the bottom two bits indicate an exit-via-index then the CPU
- * state is correctly synchronised and ready for execution of the next
- * TB (and in particular the guest PC is the address to execute next).
- * Otherwise, we gave up on execution of this TB before it started, and
- * the caller must fix up the CPU state by calling the CPU's
- * synchronize_from_tb() method with the TB pointer we return (falling
- * back to calling the CPU's set_pc method with tb->pb if no
- * synchronize_from_tb() method exists).
- *
- * Note that TCG targets may use a different definition of tcg_qemu_tb_exec
- * to this default (which just calls the prologue.code emitted by
- * tcg_target_qemu_prologue()).

+ TCG variables are the inputs and outputs of TCG ops, as described

+ with TCG variables as it emits TCG code via the tcg_gen_* functions.
+ They come in several flavours:
+ * TCGv_i32 : 32 bit integer type
+ * TCGv_i64 : 64 bit integer type
+ * TCGv_ptr : a host pointer type
+ * TCGv_vec : a host vector type; the exact size is not exposed
+ to the CPU front-end code.
+ * TCGv : an integer type the same size as target_ulong
+ (an alias for either TCGv_i32 or TCGv_i64)
+ The compiler's type checking will complain if you mix them
+ up and pass the wrong sized TCGv to a function.
+
+ Users of tcg_gen_* don't need to know about any of the internal
+ details of these, and should treat them as opaque types.
+ You won't be able to look inside them in a debugger either.
+
+ Internal implementation details follow:
+
+ Note that there is no definition of the structs TCGv_i32_d etc anywhere.
+ This is deliberate, because the values we store in variables of type
+ TCGv_i32 are not really pointers-to-structures. They're just small
+ integers, but keeping them in pointer types like this means that the
+ compiler will complain if you accidentally pass a TCGv_i32 to a
+ function which takes a TCGv_i64, and so on. Only the internals of
+ TCG need to care about the actual contents of the types. */

+ * event such as an interrupt needs handling.
+ *
+ * Return: The return value is the value passed to the corresponding
+ * tcg_gen_exit_tb() at translation time of the last TB attempted to execute.
+ * The value is either zero or a 4-byte aligned pointer to that TB combined
+ * with additional information in its two least significant bits. The
+ * additional information is encoded as follows:
+ * 0, 1: the link between this TB and the next is via the specified
+ * TB index (0 or 1). That is, we left the TB via (the equivalent
+ * of) "goto_tb <index>". The main loop uses this to determine
+ * how to link the TB just executed to the next.
+ * 2: we are using instruction counting code generation, and we
+ * did not start executing this TB because the instruction counter
+ * would hit zero midway through it. In this case the pointer
+ * returned is the TB we were about to execute, and the caller must
+ * arrange to execute the remaining count of instructions.
+ * 3: we stopped because the CPU's exit_request flag was set
+ * (usually meaning that there is an interrupt that needs to be
+ * handled). The pointer returned is the TB we were about to execute
+ * when we noticed the pending exit request.
+ *
+ * If the bottom two bits indicate an exit-via-index then the CPU
+ * state is correctly synchronised and ready for execution of the next
+ * TB (and in particular the guest PC is the address to execute next).
+ * Otherwise, we gave up on execution of this TB before it started, and
+ * the caller must fix up the CPU state by calling the CPU's
+ * synchronize_from_tb() method with the TB pointer we return (falling
+ * back to calling the CPU's set_pc method with tb->pb if no
+ * synchronize_from_tb() method exists).

From: Yonggang Luo @ 2020-09-03 7:43 UTC (permalink / raw)
To: qemu-devel; +Cc: Paolo Bonzini, Yonggang Luo
On msys2, the -I/e/path/to/qemu -L/e/path/to/qemu are not recognized by the compiler
Cause $PWD are result posix style path such as /e/path/to/qemu that can not be recognized
by mingw gcc, and `pwd -W` are result Windows style path such as E:/path/to/qemu that can
be recognized by the mingw gcc. So we replace all $PWD with $build_path that can
building qemu under msys2/mingw environment.

- * OS includes and handling of OS dependencies

- * This header exists to pull in some common system headers that

- * it (missing defines, Windows weirdness, and so on).
- *
- * To avoid getting into possible circular include dependencies, this
- * file should not include any other QEMU headers, with the exceptions
- * of config-host.h, config-target.h, qemu/compiler.h,
- * sysemu/os-posix.h, sysemu/os-win32.h, glib-compat.h and
- * qemu/typedefs.h, all of which are doing a similar job to this file
- * and are under similar constraints.
- *
- * This header also contains prototypes for functions defined in
- * os-*.c and util/oslib-*.c; those would probably be better split
- * out into separate header files.
- *
- * In an ideal world this header would contain only:
- * (1) things which everybody needs
- * (2) things without which code would work on most platforms but
- * fail to compile or misbehave on a minority of host OSes
- *
- * This work is licensed under the terms of the GNU GPL, version 2 or later.

To: qemu-devel; +Cc: Paolo Bonzini, Yonggang Luo
Install msys2 in a proper way refer to https://github.com/cirruslabs/cirrus-ci-docs/issues/699
The https://wiki.qemu.org/Hosts/W32#Native_builds_with_MSYS2 need to be updated.
There is no need of --cross-prefix, open mingw64.exe instead of msys2.exe then we don't
need the --cross-prefix, besides using ENV
MSYS: winsymlinks:nativestrict
MSYSTEM: MINGW64
CHERE_INVOKING: 1
to opening mingw64 native shell.

Please send patches more slowly. You already have several queued, and
resending them only adds confusion.

Your patch is rewriting the whole file, I think there's a git option to fix

Also the commit message should describe why it's failing. I can see you
added --strip-trailing-cr, but still it should be mentioned.
