Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

New block analysis, generation of state machine with multiple basic blocks
This commit consists of three components:
1. A new generated x86-parser that analyses instructions. For now, it
only detects the control flow of an instruction: Whether it is a
(conditional) jump, a normal instruction or a basic block boundary
2. A new function, jit_find_basic_blocks, that finds and connects basic
blocks using 1. It loosely finds all basic blocks making up a function,
i.e. it doesn't follow call or return instructions (but it does follow
all near jumps). Different from our previous analysis, it also finds
basic blocks in the strict sense that no basic block contains a jump
into the middle of another basic block
3. A new code-generating function, jit_generate, that takes the output
of 2 as input. It generates a state machine:
- Each basic block becomes a case block in a switch-table
- Each basic block ends with setting a state variable for the following basic block
- The switch-table is inside a while(true) loop, which is terminated
by return statements in basic blocks which are leaves
Additionally:
- Block linking has been removed as it is (mostly) obsoleted by these
changes. It may later be reactived for call instructions
- The code generator API has been extended to generate the code for the state machine
- The iterations of the state machine are limited in order to avoid
infinite loops that can't be interrupted

New block analysis, generation of state machine with multiple basic blocks
This commit consists of three components:
1. A new generated x86-parser that analyses instructions. For now, it
only detects the control flow of an instruction: Whether it is a
(conditional) jump, a normal instruction or a basic block boundary
2. A new function, jit_find_basic_blocks, that finds and connects basic
blocks using 1. It loosely finds all basic blocks making up a function,
i.e. it doesn't follow call or return instructions (but it does follow
all near jumps). Different from our previous analysis, it also finds
basic blocks in the strict sense that no basic block contains a jump
into the middle of another basic block
3. A new code-generating function, jit_generate, that takes the output
of 2 as input. It generates a state machine:
- Each basic block becomes a case block in a switch-table
- Each basic block ends with setting a state variable for the following basic block
- The switch-table is inside a while(true) loop, which is terminated
by return statements in basic blocks which are leaves
Additionally:
- Block linking has been removed as it is (mostly) obsoleted by these
changes. It may later be reactived for call instructions
- The code generator API has been extended to generate the code for the state machine
- The iterations of the state machine are limited in order to avoid
infinite loops that can't be interrupted

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

this will be added in a later commit.

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.

// check if write to final stack pointer would case a page fault

Handle pagefaults without JS exceptions
This commit makes the return type of most basic memory access primitives
Result, where the Err(()) case means a page fault happened, the
instruction should be aborted and execution should continue at the page
fault handler.
The following primites have a Result return type: safe_{read,write}*,
translate_address_*, read_imm*, writable_or_pagefault, get_phys_eip,
modrm_resolve, push*, pop*.
Any instruction needs to handle the page fault cases and abort
execution appropriately. The return_on_pagefault! macro has been
provided to get the same behaviour as the previously used JS exceptions
(local to the function).
Calls from JavaScript abort on a pagefault, except for
writable_or_pagefault, which returns a boolean. JS needs to check
before calling any function that may pagefault.
This commit does not yet pervasively apply return_on_pagefault!, this
will be added in the next commit.
Jitted code does not yet properly handle the new form of page faults,
this will be added in a later commit.
