2021-07-01decl: Disallow members with incomplete typesMichael Forney
Make an exception for flexible array members, though we should also check that the flexible array member, if any, is last.
2021-07-01decl: Check that struct/union has at least one memberMichael Forney
2021-07-01qbe: Reorganize struct value to reduce size to 8 bytesMichael Forney
Make the ID an unsigned int. This will make it small enough to efficiently pass struct value by value. It also simplifies things slightly.
2021-06-30stmt: Check that controlling expression is a scalar, and drop unneeded ↵Michael Forney
conversion The conversion is only needed for floating types. QBE isn't able to optimize it away for integer types yet, so removing this unnecessary conversion has a substantial performance benefit.
2021-06-30qbe: Move aggregate copying to separate functionMichael Forney
2021-06-30qbe: Remove before unnecessary adds during copyMichael Forney
2021-06-28Add stringconcat function to concatenate adjacent string literalsMichael Forney
This function also ensures that the string prefixes (if any) are compatible. It should make it easier to implement wide string support.
2021-06-16Add initial NetBSD supportMichael Forney
2021-05-02expr: Include NUL-terminator in string expression dataMichael Forney
This will facilitate the support of wide-string literals. Based on patch from Nihal Jere.
2021-05-02qbe: Use fixed precision of 17 when printing floating point constantsMichael Forney
It appears that some operating systems don't yet support the C11 DBL_DECIMAL_DIG. In order to ensure consistent output no matter the precision of long double (which varies from arch to arch), just use a fixed 17, which is sufficient for IEEE 754 binary64.
2021-04-23Make some static data constMichael Forney
2021-04-23targ: Use correct char signedness for aarch64 and riscv64Michael Forney
2021-04-22Update test for DBL_DECIMAL_DIGMichael Forney
2021-04-21qbe: Print floating point with DBL_DECIMAL_DIG precisionMichael Forney
DECIMAL_DIG may vary from system to system depending on the width of long double, causing one of the tests to fail.
2021-04-21CI: Pin FreeBSD to 12.x for nowMichael Forney
FreeBSD 13 no longer contains a standalone assembler in the base install, and also added a hard-requirement on _Thread_local.
2021-04-21Add support for riscv64 targetMichael Forney
QBE support isn't quite there yet, but is progressing smoothly.
2021-04-11Check in static-assert-struct test expected outputMichael Forney
2021-04-11decl: Allow _Static_assert in struct declarationMichael Forney
2021-04-11decl: Allow _Alignas(0)Michael Forney
C11 6.7.5p6 says "An alignment specification of zero has no effect".
2021-04-08qbe: Remove unnecessary value copy for struct/union typesMichael Forney
Previously, this was needed so that an aggregate type value was updated to be an 'l' type value. However, since 5ff1d2fa the aggregate type name is stored in a separate parameter in IARG/ICALL instructions, so we can just re-use the same pointer value.
2021-04-08Remove unused mkswitch declarationMichael Forney
2021-04-08CI: Fix debian-aarch64 dependency packagesMichael Forney
It appears that these packages recommended by gcc-aarch64-linux-gnu and qemu-user are no longer installed automatically, so list them explicitly.
2021-04-08qbe: Remove unnecessary extension for relational operandsMichael Forney
The operands are already promoted, so never need to be extended. These extend()s were added in 7d746860 in an attempt to fix a bug related to the comparison of values with type smaller than int. However, the real bug was that the operands should have been promoted to int by usual arithmetic conversions, which was fixed later in a8131372.
2021-04-07qbe: Remove __PRETTY_FUNCTION__ declarationMichael Forney
We no longer define __GNUC__ so we don't have to work around glibc's assert definition anymore.
2021-04-06qbe: Shorten a few overly long linesMichael Forney
2021-03-31qbe: Slight simplificationMichael Forney
2021-03-31qbe: Use second argument of call/arg to store type nameMichael Forney
2021-03-31qbe: Use separate type for block/labelMichael Forney
Labels are no longer used as instruction arguments.
2021-03-31qbe: Switch to fixed-size instruction structMichael Forney
Move jump and phi instructions to struct block, and function arguments to their own instruction. This will facilitate allocating instructions as an array.
2021-03-30Add struct passing call testMichael Forney
The struct-passing test checks for function definitions with struct arguments, but we were missing a test for function calls with struct arguments.
2021-03-27qbe: Change value kind naming schemeMichael Forney
2020-12-07CI: Drop obsolete OpenBSD patchMichael Forney
2020-12-07Support -pthread compiler flag.Érico Rolim
POSIX requires -lpthread, but most Linux manual pages recommend using -pthread, and a lot of projects use it.
2020-10-21Update qbe submoduleMichael Forney
2020-09-12Update qbe submoduleMichael Forney
2020-09-05Add a patch to fix OpenBSD bootstrap on 6.7Michael Forney
This issue is already fixed in -current.
2020-09-05Add -nopie to linker flags on OpenBSDMichael Forney
The OpenBSD linker defaults to PIE, but QBE does not yet support generating position-independent code.
2020-06-29.builds/alpine: remove annotationsDrew DeVault
This feature is being removed from git.sr.ht
2020-06-05Help gcc see that variables are not used uninitializedMichael Forney
2020-06-03Revert "decl: Allow out-of-range enum constants when they don't change type"Michael Forney
This reverts commit 6229709b8ae21d7722fef48ad8a9f2f10b900030. I still don't understand how out-of-range enum constants are supposed to work.
2020-06-03Disable bootstrap in OpenBSD continuous buildMichael Forney
2020-06-03decl: Allow out-of-range enum constants when they don't change typeMichael Forney
gcc and clang allow enum constants out of range of int, but this means that the type of enumerator may differ inside and outside the enum specifier. Instead, only allow out-of-range enum constants when their types are compatible with the final enum type.
2020-06-02decl: Improve error message for out-of-range enum constantsMichael Forney
2020-05-24qbe: Omit unnecessary add to help QBE's memopt passMichael Forney

2020-04-14Refer to github issue for oasis porting effortMichael Forney
2020-04-05expr: Just ignore decayed operand in unary `&` operatorMichael Forney
Reusing the decayed expression is more complicated, and only saved one malloc.
