|\ | | | | | | | | | | | | * commit '41cf3e3b1ca375962951fde1b90a03b16197d205': arm: Create proper .rdata sections for COFF Merged-by: James Almer <jamrial@gmail.com>
| * arm: Create proper .rdata sections for COFFMartin Storsjö2019-01-25
| | | | | | | | | | | | | | | | | | | | | | | | As .rodata isn't one of the default created sections for COFF, it was created as a read-write data section. By using the default .rdata section name for COFF, it automatically becomes a read-only data section. The existing ".section .rodata" works as intended for ELF though. This is based on an original patch and diagnose by Tom Tan <Tom.Tan@microsoft.com>. Signed-off-by: Martin Storsjö <martin@martin.st>

| * arm: Emit .thumb_func directivesMartin Storsjö2018-10-12
| | | | | | | | | | | | | | | | | | | | | | Prior to Xcode 9.3, the clang built-in assembler didn't support altmacro, and gas-preprocessor was used for assembling for arm/darwin. For thumb functions, gas-preprocessor took care of adding the .thumb_func directives, but when now being able to assemble without gas-preprocessor, we need to add these directives ourselves.

| | | | | | | | | | | | | | | | | | | | This is the same combination of .section directives as used in aarch64/asm.S. Since Xcode 9.3, the bundled clang supports altmacro and doesn't require using gas-preprocessor any longer. Signed-off-by: Martin Storsjö <martin@martin.st>

| * arm: Check for the .arch directive in configureMartin Storsjö2017-05-08
| | | | | | | | | | | | | | | | | | | | | | | | When targeting windows, the .arch directive isn't available. So far, when building for windows, we've always used gas-preprocessor, both when using msvc's armasm and when using clang. Lately, clang/llvm has implemented the last missing piece (altmacro support) for building our assembly without gas-preprocessor. This means that we now build for arm/windows with clang without any extra compatibility layer. Signed-off-by: Martin Storsjö <martin@martin.st>

| * arm: warn/error on movrelx usage problematic with PIC on ELFJanne Grunau2016-11-24
| | | | | | | | | | | | The warning has false positives but our asm does not trigger it. For new code false positives can only be avoided by changing the register allocation.
| * arm: Clear the gp register alias at the end of functionsMartin Storsjö2016-11-10
| | | | | | | | | | | | | | | | | | | | | | We reset .Lpic_gp to zero at the start of each function, which means that the logic within movrelx for clearing gp when necessary will be missed. This fixes using movrelx in different functions with a different helper register. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | | | When all the codepaths using manually set .arch/.fpu code is behind runtime detection, the elf attributes should be suppressed.

| * arm: Add EXTERN_ASM to the .func and .type declarations for exported symbolsMartin Storsjö2014-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the generated assembly more internally consistent, avoiding declaring two labels for the same function (for cases where EXTERN_ASM is empty) and not declaring a separate unprefixed label in other cases. This also makes sure the .func and .type delcarations have the same prefix. They have previously not been used on the platforms that have prefixed symbols on arm (iOS), but gas-preprocessor has recently started using the .func declarations for adding .thumb_func declarations for such functions.

| * arm: Allow overriding the alignment set in the function macroMartin Storsjö2014-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function macro always sets .align 2 before declaring the function label (since 5c5e1ea3) and always sets the section to .text (since 278caa6a). The .align 5 before certain functions, added in fc252eba, were added before .text and .align were added to the function macro and thus became useless/unused when the function macro got them. This restores the original intention, to align the loop entry points. Signed-off-by: Martin Storsjö <martin@martin.st>
