+Subject: [PATCH] target: default to the medium code model on LoongArch targets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rust LoongArch targets have been using the default LLVM code model
+so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak.
+As described in the "Code Model" section of LoongArch ELF psABI spec
+v20231219 [1], one can only make function calls as far as ±128MiB with
+the "normal" code model; this is insufficient for very large software
+containing Rust components that needs to be linked into the big text
+section, such as Chromium.
+
+Because:
+
+* we do not want to ask users to recompile std if they are to build
+ such software,
+* objects compiled with larger code models can be linked with those
+ with smaller code models without problems, and
+* the "medium" code model is comparable to the "small"/"normal" one
+ performance-wise (same data access pattern; each function call
+ becomes 2-insn long and indirect, but this may be relaxed back into
+ the direct 1-insn form in a future LLVM version), but is able to
+ perform function calls within ±128GiB,
+
+it is better to just switch the targets to the "medium" code model,
+which is also "medium" in LLVM-speak.

+Subject: [PATCH] target: default to the medium code model on LoongArch targets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rust LoongArch targets have been using the default LLVM code model
+so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak.
+As described in the "Code Model" section of LoongArch ELF psABI spec
+v20231219 [1], one can only make function calls as far as ±128MiB with
+the "normal" code model; this is insufficient for very large software
+containing Rust components that needs to be linked into the big text
+section, such as Chromium.
+
+Because:
+
+* we do not want to ask users to recompile std if they are to build
+ such software,
+* objects compiled with larger code models can be linked with those
+ with smaller code models without problems, and
+* the "medium" code model is comparable to the "small"/"normal" one
+ performance-wise (same data access pattern; each function call
+ becomes 2-insn long and indirect, but this may be relaxed back into
+ the direct 1-insn form in a future LLVM version), but is able to
+ perform function calls within ±128GiB,

+Subject: [PATCH] target: default to the medium code model on LoongArch targets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rust LoongArch targets have been using the default LLVM code model
+so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak.
+As described in the "Code Model" section of LoongArch ELF psABI spec
+v20231219 [1], one can only make function calls as far as ±128MiB with
+the "normal" code model; this is insufficient for very large software
+containing Rust components that needs to be linked into the big text
+section, such as Chromium.
+
+Because:
+
+* we do not want to ask users to recompile std if they are to build
+ such software,
+* objects compiled with larger code models can be linked with those
+ with smaller code models without problems, and
+* the "medium" code model is comparable to the "small"/"normal" one
+ performance-wise (same data access pattern; each function call
+ becomes 2-insn long and indirect, but this may be relaxed back into
+ the direct 1-insn form in a future LLVM version), but is able to
+ perform function calls within ±128GiB,
+
+it is better to just switch the targets to the "medium" code model,
+which is also "medium" in LLVM-speak.

+Subject: [PATCH] target: default to the medium code model on LoongArch targets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rust LoongArch targets have been using the default LLVM code model
+so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak.
+As described in the "Code Model" section of LoongArch ELF psABI spec
+v20231219 [1], one can only make function calls as far as ±128MiB with
+the "normal" code model; this is insufficient for very large software
+containing Rust components that needs to be linked into the big text
+section, such as Chromium.
+
+Because:
+
+* we do not want to ask users to recompile std if they are to build
+ such software,
+* objects compiled with larger code models can be linked with those
+ with smaller code models without problems, and
+* the "medium" code model is comparable to the "small"/"normal" one
+ performance-wise (same data access pattern; each function call
+ becomes 2-insn long and indirect, but this may be relaxed back into
+ the direct 1-insn form in a future LLVM version), but is able to
+ perform function calls within ±128GiB,
+
+it is better to just switch the targets to the "medium" code model,
+which is also "medium" in LLVM-speak.

+Subject: [PATCH] target: default to the medium code model on LoongArch targets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rust LoongArch targets have been using the default LLVM code model
+so far, which is "small" in LLVM-speak and "normal" in LoongArch-speak.
+As described in the "Code Model" section of LoongArch ELF psABI spec
+v20231219 [1], one can only make function calls as far as ±128MiB with
+the "normal" code model; this is insufficient for very large software
+containing Rust components that needs to be linked into the big text
+section, such as Chromium.
+
+Because:
+
+* we do not want to ask users to recompile std if they are to build
+ such software,
+* objects compiled with larger code models can be linked with those
+ with smaller code models without problems, and
+* the "medium" code model is comparable to the "small"/"normal" one
+ performance-wise (same data access pattern; each function call
+ becomes 2-insn long and indirect, but this may be relaxed back into
+ the direct 1-insn form in a future LLVM version), but is able to
+ perform function calls within ±128GiB,
+
+it is better to just switch the targets to the "medium" code model,
+which is also "medium" in LLVM-speak.
